[ 146/153] usermodehelper: ____call_usermodehelper() doesnt need do_exit()

[Ben Hutchings]

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Oleg Nesterov <oleg@xxxxxxxxxx>

commit 5b9bd473e3b8a8c6c4ae99be475e6e9b27568555 upstream.

Minor cleanup.  ____call_usermodehelper() can simply return, no need to
call do_exit() explicitely.
