RDMA/irdma: Annotate flexible array with __counted_by() in struct irdma_qvlist_info

'num_vectors' is used to count the number of elements in the 'qv_info'
flexible array in "struct irdma_qvlist_info".

So annotate it with __counted_by() to make it explicit and enable some
additional checks.

This allocation is done in irdma_save_msix_info().
