Fix failure to resume from initrds
Commit 831441862956fffa17b9801db37e6ea1650b0f69 (Freezer: make kernel threads nonfreezable by default) breaks freezing when attempting to resume from an initrd, because the init (which is freezeable) spins while waiting for another thread to run /linuxrc, but doesn't check whether it has been told to enter the refrigerator. The original patch replaced a call to try_to_freeze() with a call to yield(). I believe a simple reversion is wrong because if !CONFIG_PM_SLEEP, try_to_freeze() is a noop. It should still yield.
