RDMA/bnxt_re: Add send queue size check for variable wqe

Browse source

[ Upstream commit d13be54dc1 ]

For the fixed WQE case, HW supports 0xFFFF WQEs.
For variable Size WQEs, HW treats this number as
the 16 bytes slots. The maximum supported WQEs
needs to be adjusted based on the number of slots.
Set a maximum WQE limit for variable WQE scenario.
