[PATCH] get rid of __exit_files(), __exit_fs() and __put_fs_struct()

The only reason to have separated __...() for those was to keep them inlined
for local users in exit.c.  Since Alexey removed the inline on those, there's
no reason whatsoever to keep them around; just collapse with normal variants.
