The VF really doesn't care about the QOS handle but it will in the
future. Since the VF only uses TC0, send it that handle. On the VF
side, save the handle and use it to populate the QOS params when we call
into the client interface.

Using VFGEN_RSTAT to detect a VF reset is an endeavor that is fraught
with peril. It's entirely too easy to miss a reset because none of the
bits are sticky. By the time the VF driver reads the register, the reset
may have been processed and cleaned up by the PF driver, leaving the
register in the same state that it was before the reset.
Instead, detect a reset with the VF_ARQLEN register. When the VF is
reset, the enable bit in this register is cleared, and it stays cleared
until the VF driver processes the reset and re-enables the admin queue.
Because we now deal with multiple registers in the reset and watchdog
tasks, rename the rstat_val variable to reg_val.

The change is to explicitly assign enum index for each VSI type

Additionally, move the 'Allocating VFs' message down below the error

When using something like "ip maddr add ..." to add another unicast mac
address to the netdev, the mac address comes into the set_rx_mode handler
in the multicast list whether it is a unicast or multicast address.
This was confusing the code when it was trying to search for addresses
that needed to be deleted from the VSI, because it was looking for the
VSI unicast address in the netdev unicast list. The result was that a
new unicast address would get added to the VSI list and then immediately
removed, and would never actually make it down into the hardware.
This patch removes the separation from unicast and multicast in the search
for filters to be deleted. It also simplifies the logic a little with a
jump to the bottom of the loop when an address is found. Now it doesn't
matter which netdev list the address is hiding in, we'll check them all.

Previously, the driver could call this function and have only true/false
returned, but false could mean multiple things like failure to read
or link was down. This change allows the caller to get all return values
in the call chain bubbled back to the source, which keeps information about
failures from being lost.
Also, in some unlikely scenarios, the firmware can become slow to respond
to admin queue (AQ) queries for link state. Should the AQ time out,
the driver can detect the state and avoid a link change when there
may have been none.
