RDMA/bnxt_re: Fix budget handling of notification queue
The cited commit in Fixes tag introduced a bug which can cause hang
of completion queue processing because of notification queue budget
goes to zero.
Found while doing nfs over rdma mount and umount.
Below message is noticed because of the existing bug.
kernel: cm_destroy_id_wait_timeout: cm_id=00000000ff6c6cc6 timed out. state 11 -> 0, refcnt=1
Fix to handle this issue -
Driver will not change nq->budget upon create and destroy of cq and srq
rdma resources.
Fixes: cb97b377a135 ("RDMA/bnxt_re: Refurbish CQ to NQ hash calculation")
