Subject: [PATCH v1 09/11] scsi: ufs: fix condition in which DME command failure msg is printed out

From: Yaniv Gardi <ygardi@...eaurora.org>

The condition in which error message is printed out was incorrect and
resulted error message only if retries exhausted.
But retries happens only if DME command is a peer command, and thus
DME commands which are not peer commands and fail are not printed out.
This change fixes this issue.
