[PATCH] PCI: altera: remove unused num_of_vectors variable

[Shawn Lin <shawn.lin@rock-chips.com>]

It was never used and could be removed, otherwise
we could see a warning:

drivers/pci/host/pcie-altera-msi.c: In function 'altera_msi_isr':
drivers/pci/host/pcie-altera-msi.c:67:6: warning: variable
'num_of_vectors' set but not used [-Wunused-but-set-variable]
