virtio-pci: Remove wrong address verification in vp_del_vqs() ...
commit 7e415282b41bf0d15c6e0fe268f822d9b083f2f7 upstream.
GCC 12 enhanced -Waddress when comparing array address to null [0],
which warns:
drivers/virtio/virtio_pci_common.c: In function ‘vp_del_vqs’:
drivers/virtio/virtio_pci_common.c:257:29: warning: the comparison will always evaluate as ‘true’ for the pointer operand in ‘vp_dev->msix_affinity_masks + (sizetype)((long unsigned int)i * 256)’ must not be NULL [-Waddress]
257 | if (vp_dev->msix_affinity_masks[i])
| ^~~~~~
In fact, the verification is comparing the result of a pointer
arithmetic, the address "msix_affinity_masks + i", which will always
evaluate to true.
Under the hood, free_cpumask_var() calls kfree(), which is safe to pass
NULL, not requiring non-null verification. So remove the verification
to make compiler happy (happy compiler, happy life).
