Regression introduced by commit 258e06c85b7, "ret" could be set to 1
or 0 by virStorageBackendFileSystemIsMounted before goto cleanup.
This could mislead the callers (up to the public API

command fails.

This if statement is redundant and could be replaced with
return rc;
return -1;
else
return 0;
ACK with that change.
