pstore: Improve error reporting in case of backend overlap
The pstore infrastructure supports one single backend at a time;
trying to load a another backend causes an error and displays a
message, introduced on commit 0d7cd09a3dbb ("pstore: Improve
register_pstore() error reporting").
Happens that this message is not really clear about the situation,
also the current error returned (-EPERM) isn't accurate, whereas
-EBUSY makes more sense. We have another place in the code that
relies in the -EBUSY return for a similar check.
So, make it consistent here by returning -EBUSY and using a
similar message in both scenarios.
