qla2x00t-32gbit: Backport to older kernel versions

Browse Source 
Commit ccf2e9c8fab7 ("qla2x00t-32gbit: Select qpair depending on which
CPU post_cmd() gets called") introduced an optimization based on the
pci_irq_get_affinity() API.

Due to support for older kernel versions, limit the minimum kernel
version to use this optimization to v4.9.

See also commit ee8d41e53efe ("pci/msi: Retrieve affinity for a vector") # v4.9.
