## Description

In the Linux kernel, the following vulnerability has been resolved:

wifi: ath11k: Clear affinity hint before calling ath11k_pcic_free_irq() in error path

If a shared IRQ is used by the driver due to platform limitation, then the
IRQ affinity hint is set right after the allocation of IRQ vectors in
ath11k_pci_alloc_msi(). This does no harm unless one of the functions
requesting the IRQ fails and attempt to free the IRQ. This results in the
below warning:

WARNING: CPU: 7 PID: 349 at kernel/irq/manage.c:1929 free_irq+0x278/0x29c
Call trace:
 free_irq+0x278/0x29c
 ath11k_pcic_free_irq+0x70/0x10c [ath11k]
 ath11k_pci_probe+0x800/0x820 [ath11k_pci]
 local_pci_probe+0x40/0xbc

The warning is due to not clearing the affinity hint before freeing the
IRQs.

So to fix this issue, clear the IRQ affinity hint before calling
ath11k_pcic_free_irq() in the error path. The affinity will be cleared once
again further down the error path due to code organization, but that does
no harm.
