RDMA/irdma: Make spdxcheck.py happy

Commit 48d6b3336a9f ("RDMA/irdma: Add ABI definitions") adds
./include/uapi/rdma/irdma-abi.h with an additional unneeded closing
bracket at the end of the SPDX-License-Identifier line.

Hence, ./scripts/spdxcheck.py complains:

  include/uapi/rdma/irdma-abi.h: 1:77 Syntax error: )

Remove that closing bracket to make spdxcheck.py happy.
