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.
