nvmet: return a specified error it subsys_alloc fails
nvmet_subsys_alloc() returns its pointer or NULL if it fails. We can
see three different steps in this function:
1. memory allocation
2. argument check
3. memory allocation for string
But now the callers of this function do not seem to handle case 2 by
returning -ENOMEM only even if it fails with an invalid parameter.
This patch specifies error codes so that caller can pass it to its own
caller.
