[ Upstream commit 09a89cc59ad67794a11e1d3dd13c5b3172adcc51 ]
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.
Fixes: b16b68918674 ("bnxt_en: Add SR-IOV support for 57500 chips.")
