[PATCH 2/2] Freezer: Fix JFFS2 garbage collector freezing issue

["Rafael J. Wysocki" <rjw@xxxxxxx>]

From: Rafael J. Wysocki <rjw@xxxxxxx>

Fix breakage caused by commit d5d8c5976d6adeddb8208c240460411e2198b393
"freezer: do not send signals to kernel threads" in
jffs2_garbage_collect_thread() that assumed it would be sent signals
by the freezer.
