Currently netfilter's rpfilter and fib modules implicitely initialise
->flowic_uid with 0. This is normally the root UID. However, this isn't
the case in user namespaces, where user ID 0 is mapped to a different
kernel UID. By initialising ->flowic_uid with sock_net_uid(), we get
the root UID of the user namespace, thus keeping the same behaviour
whether or not we're running in a user namepspace.
Note, this is similar to commit 8bcfd0925e ("ipv4: add missing
initialization for flowi4_uid"), which fixed the rp_filter sysctl.

It's possible that the driver will dereference a qcq that doesn't exist
when calling ionic_reconfigure_queues(), which causes a page fault BUG.
If a reduction in the number of queues is followed by a different
reconfig such as changing the ring size, the driver can hit a NULL
pointer when trying to clean up non-existent queues.
Fix this by checking to make sure both the qcqs array and qcq entry
exists bofore trying to use and free the entry.

When booting a kernel compiled with CONFIG_CFI_CLANG on a machine with
an RX 6700 XT, there is a CFI failure in kfd_destroy_mqd_cp():
[ 12.894543] CFI failure at kfd_destroy_mqd_cp+0x2a/0x40 [amdgpu] (target: hqd_destroy_v10_3+0x0/0x260 [amdgpu]; expected type: 0x8594d794)
Clang's kernel Control Flow Integrity (kCFI) makes sure that all
indirect call targets have a type that exactly matches the function
pointer prototype. In this case, hqd_destroy()'s third parameter,
reset_type, should have a type of 'uint32_t' but every implementation of
this callback has a third parameter type of 'enum kfd_preempt_type'.
Update the function pointer prototype to match reality so that there is
no more CFI violation.

The following tests were run by doing 60 seconds of random reads using
a dm-verity device backed by two ramdisks.
Without WQ_HIGHPRI
lat (usec): min=13, max=3947, avg=69.53, stdev=50.55
READ: bw=51.1MiB/s (53.6MB/s), 51.1MiB/s-51.1MiB/s (53.6MB/s-53.6MB/s)
With WQ_HIGHPRI:

READ: bw=116MiB/s (121MB/s), 116MiB/s-116MiB/s (121MB/s-121MB/s)
Further testing was done by measuring how long it takes to open a
camera on an Android device.
Without WQ_HIGHPRI
Total verity work queue wait times (ms):
880.960, 789.517, 898.852
