RDMA/bnxt_re: Do not add user qps to flushlist

Browse Source 
Driver shall add only the kernel qps to the flush list for clean up.
During async error events from the HW, driver is adding qps to this list
without checking if the qp is kernel qp or not.

Add a check to avoid user qp addition to the flush list.

Fixes: 942c9b6ca8de ("RDMA/bnxt_re: Avoid Hard lockup during error CQE processing")
Fixes: c50866e2853a ("bnxt_re: fix the regression due to changes in alloc_pbl")
