[linux-pm] [PATCH] fix windfarm core thread wrt. signal handling

[johannes at sipsolutions.net (Johannes Berg)]

This patch removes the signal_pending() from the windfarm core thread
loop as it isn't necessary and messes up when there actually *is* a
signal pending because we should enter the freezer.
