RDMA/hns: Fix the modification of max_send_sge

Browse Source 
[ Upstream commit f5a7cbea5411668d429eb4ffe96c4063fe8dac9e ]

The actual sge number may exceed the value specified in init_attr->cap
when HW needs extra sge to enable inline feature. Since these extra
sges are not expected by ULP, return the user-specified value to ULP
instead of the expanded sge number.
