[PATCH 1/4] nvmet: fix return status of RMI log page on allocation failure

nvmet_execute_get_log_page_rmi() leaves 'status' holding NVME_SC_SUCCESS
(set by the successful nvmet_req_find_ns() call) when the kzalloc() for
the log buffer fails. It then jumps to the out label and completes the
request with a success status, so the host is told the command succeeded
while no data was transferred.

Initialize 'status' to NVME_SC_INTERNAL, matching the smart log handler,
so an allocation failure is reported as an internal error.

Fixes: 5fd075cdaf36 ("nvmet: implement rotational media information log")
