RDMA/cxgb4: add missing qpid increment

Browse Source 
missing qpid increment leads to skipping few qpids while allocating QP.
This eventually leads to adapter running out of qpids after establishing
fewer connections than it actually supports.
Current patch increments the qpid correctly.

Fixes: cfdda9d764 ("RDMA/cxgb4: Add driver for Chelsio T4 RNIC")
