[ Upstream commit bc9da6dd0630efd81b5c72ff6fa0169aa029a73f ]

commit 1243172d5894 ("nbd: use pr_err to output error message") tries
to define pr_fmt and use short pr_err() to output error message,
however, the definition is missed.

This patch also remove existing "nbd:" inside pr_err().

Fixes: 1243172d5894 ("nbd: use pr_err to output error message")
