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.

Typically, this #define is place before all #include lines
so there is no need for an #undef

Thanks for you advice, I'll do that in v2.
