Subject: util: Set errno in error case nvme_get_directive_receive_length
X-Git-Tag: v1.0-rc2~4^2

util: Set errno in error case nvme_get_directive_receive_length

The API says we return -1 in the error case and set the errno
accordingly. Update nvme_get_directive_receive_length
to fulfill the promise.
