From: Kalesh AP <kalesh-anakkur.purayil@xxxxxxxxxxxx>
Inside bnxt_qplib_create_cq(), when the check for NULL DPI
fails, driver returns directly without freeing the memory
allocated inside bnxt_qplib_alloc_init_hwq() routine.
Fixed this by moving the check for NULL DPI before invoking
bnxt_qplib_alloc_init_hwq().
Fixes: 1ac5a4047975 ("RDMA/bnxt_re: Add bnxt_re RoCE driver")
