RDMA/bnxt_re: Fix incorrect AVID type in WQE structure

Browse Source 
[ Upstream commit 9ab20f76ae ]

Driver uses internal data structure to construct WQE frame.
It used avid type as u16 which can accommodate up to 64K AVs.
When outstanding AVID crosses 64K, driver truncates AVID and
hence it uses incorrect AVID to WR. This leads to WR failure
due to invalid AV ID and QP is moved to error state with reason
set to 19 (INVALID AVID). When RDMA CM path is used, this issue
hits QP1 and it is moved to error state
