The logic needs to check both bp->total_irqs and the reserved IRQs in
hw_resc->resv_irqs if applicable and see if both are enough to cover
the L2 and RDMA requested vectors.  The current code is only checking
bp->total_irqs and can fail in some code paths, such as the TX timeout
code path with the RDMA driver requesting vectors after recovery.  In
this code path, we have not reserved enough MSIX resources for the
RDMA driver yet.
