RDMA/efa: Add checksum support for admin responses

EFA devices added support for CRC16 checksum on admin responses and to
expose it to the driver the API version increased to 0.2. Add a check
for support on device init and if supported validate the checksum on
each admin response the driver receives. If the checksum validation
failed, drop the CQE.

Add the CRC16 module to Kconfig to have the in-tree dependency.
