Subject: [PATCH] exfat: fix ctime is not updated
Commit 4c72a36edd54 ("exfat: convert to new timestamp accessors")
removed attr_copy() from exfat_set_attr().
It causes xfstests generic/221 to fail. In xfstests generic/221,
it tests ctime should be updated even if futimens() update atime
only. But in this case, ctime will not be updated if attr_copy()
is removed.
attr_copy() may also update other attributes, and removing it may
cause other bugs, so this commit restores to call attr_copy() in
exfat_set_attr().
