storage: Fix bug of fs pool destroying

Browse Source 
Regression introduced by commit 258e06c85b, "ret" could be set to 1
or 0 by virStorageBackendFileSystemIsMounted before goto cleanup.
This could mislead the callers (up to the public API
virStoragePoolDestroy) to return success even the underlying umount
command fails.
(cherry picked from commit f4ac06569a)
