crypto: nitrox - fix unchecked variable in nitrox_register_interrupts

Browse Source 
[ Upstream commit 57c126661f50b884d3812e7db6e00f2e778eccfb ]

Function nitrox_register_interrupts leaves variable 'nr_vecs' unchecked, which
would be use as kcalloc parameter later.

Fixes: 5155e118dd ("crypto: cavium/nitrox - use pci_alloc_irq_vectors() while enabling MSI-X.")
