RDMA/bnxt_re: Fix entry size during SRQ create
[ Upstream commit b898d5c50cab1f985e77d053eb5c4d2c4a7694ae ]
Only static WQE is supported for SRQ. So always use the max supported SGEs
while calculating SRQ entry size.
Fixes: 2bb3c32c5c5f ("RDMA/bnxt_re: Change wr posting logic to accommodate variable wqes")
