[ Upstream commit 09a89cc5 ]

There are 2 issues:

1. We should decrement hw_resc->max_nqs instead of hw_resc->max_irqs
   with the number of NQs assigned to the VFs.  The IRQs are fixed
   on each function and cannot be re-assigned.  Only the NQs are being
   assigned to the VFs.

2. vf_msix is the total number of NQs to be assigned to the VFs.  So
   we should decrement vf_msix from hw_resc->max_nqs.
