Subject: net/mlx5: Allocate virtually contiguous memory in pci_irq.c
Patch-mainline: v5.19-rc1
Git-commit: 88468311c07a8bb34321166341f93981f7337a7d
References: jsc#PED-1549
Physical continuity is not necessary, and requested allocation size might
be larger than PAGE_SIZE.
Hence, use v-alloc/free API.
