[ Upstream commit ff132c5f93c06bd4432bbab5c369e468653bdec4 ]
Before this patch, gfs2's freeze function failed to report an error
when the target file system was already frozen as it should (and as
generic vfs function freeze_super does. Similarly, gfs2's thaw function
failed to report an error when trying to thaw a file system that is not
frozen, as vfs function thaw_super does. The errors were checked, but
it always returned a 0 return code.
This patch adds the missing error return codes to gfs2 freeze and thaw.
