nvmf: remove double immediate completion handling

Browse Source 
The "immediate completion" cases in spdk_nvmf_request_exec() already
call spdk_nvmf_request_complete(), so the ret == 1 case in nvmf_recv()
is bogus.

Also fix a couple of spdk_nvmf_request_complete() calls in
nvmf_process_admin_cmd() that should be handled by its caller.
