[PATVH V2 3/3] nvmet: call blk_mq_free_request() directly

[Chaitanya Kulkarni]

Instead of calling blk_put_request() which calls blk_mq_free_request(),
call blk_mq_free_request() directly for NVMeOF passthru. This is to
mainly avoid an extra function call in the completion path
nvmet_passthru_req_done().
