Kashyap Desai 3de1b50f05 RDMA/bnxt_re: Fix max SGEs for the Work Request 
commit 79d330fbdf upstream.

Gen P7 supports up to 13 SGEs for now. WQE software structure
can hold only 6 now. Since the max send sge is reported as
13, the stack can give requests up to 13 SGEs. This is causing
traffic failures and system crashes.

Use the define for max SGE supported for variable size. This
will work for both static and variable WQEs.
