Eryk Rybak 347b5650cd i40e: Fix kernel oops when i40e driver removes VF's
Fix the reason of kernel oops when i40e driver removed VFs.
Added new __I40E_VFS_RELEASING state to signalize releasing
process by PF, that it makes possible to exit of reset VF procedure.
Without this patch, it is possible to suspend the VFs reset by
releasing VFs resources procedure. Retrying the reset after the
timeout works on the freed VF memory causing a kernel oops.

Fixes: d43d60e5eb ("i40e: ensure reset occurs when disabling VF")

/* TOTAL_PORT_SHUTDOWN
* Allows to physically disable the link on the NIC's port.
* If enabled, (after link down request from the OS)
* no link, traffic or led activity is possible on that port.
*
* If I40E_FLAG_TOTAL_PORT_SHUTDOWN_ENABLED is set, the
* I40E_FLAG_LINK_DOWN_ON_CLOSE_ENABLED must be explicitly forced to true
* and cannot be disabled by system admin at that time.
* The functionalities are exclusive in terms of configuration, but they also
* have similar behavior (allowing to disable physical link of the port),
* with following differences:
* - LINK_DOWN_ON_CLOSE_ENABLED is configurable at host OS run-time and is
* supported by whole family of 7xx Intel Ethernet Controllers
* - TOTAL_PORT_SHUTDOWN may be enabled only before OS loads (in BIOS)
* only if motherboard's BIOS and NIC's FW has support of it
* - when LINK_DOWN_ON_CLOSE_ENABLED is used, the link is being brought down
* by sending phy_type=0 to NIC's FW
* - when TOTAL_PORT_SHUTDOWN is used, phy_type is not altered, instead
* the link is being brought down by clearing bit (I40E_AQ_PHY_ENABLE_LINK)
* in abilities field of i40e_aq_set_phy_config structure
