RDMA/bnxt_re: Avoid clearing VLAN_ID mask in modify qp path

Browse Source 
[ Upstream commit 81c0db302a674f8004ed805393d17fd76f552e83 ]

Driver is always clearing the mask that sets the VLAN ID/Service Level
in the adapter. Recent change for supporting multiple traffic class
exposed this issue.

Allow setting SL and VLAN_ID while QP is moved from INIT to RTR state.

Fixes: 1ac5a40479 ("RDMA/bnxt_re: Add bnxt_re RoCE driver")
Fixes: c64b16a37b6d ("RDMA/bnxt_re: Support different traffic class")
