RDMA/bnxt_re: Simplify the function that sends the FW commands

Browse source

[ Upstream commit 159cf95e42 ]

 - Use __send_message_basic_sanity helper function.
 - Do not retry posting same command if there is a queue full detection.
 - ENXIO is used to indicate controller recovery.
 - In the case of ERR_DEVICE_DETACHED state, the driver should not post
   commands to the firmware, but also return fabricated written code.
