qla2xxx: Use pci_enable_msix_range() instead of pci_enable_msix()
As result of deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range() or pci_enable_msi_exact()
and pci_enable_msix_range() or pci_enable_msix_exact()
interfaces.
Log message code 0x00c6 preserved, although it is reported
after successful call to pci_enable_msix_range(), not before
possibly unsuccessful call to pci_enable_msix(). Consumers
of the error code should not notice the difference.
