Majd Dibbiny d3957b86a4 RDMA/SA: Fix kernel panic in CMA request handler flow ... Commit 9fdca4da4d (IB/SA: Split struct sa_path_rec based on IB and ROCE specific fields) moved the service_id to be specific attribute for IB and OPA SA Path Record, and thus wasn't assigned for RoCE. This caused to the following kernel panic in the CMA request handler flow: [ 27.074594] BUG: unable to handle kernel NULL pointer dereference at 0000000000000008 [ 27.074731] IP: __radix_tree_lookup+0x1d/0xe0 ...

Tested on Connect-IB and Connect-X4 in Infiniband and RoCE respectively.
