Jason Gunthorpe 515f60004e RDMA/hns: Prevent undefined behavior in hns_roce_set_user_sq_size() 
The "ucmd->log_sq_bb_count" variable is a user controlled variable in the
0-255 range.  If we shift more than then number of bits in an int then
it's undefined behavior (it shift wraps), and potentially the int could
become negative.

Fixes: 9a4435375c ("IB/hns: Add driver files for hns RoCE driver")
