Subject: staging: unisys: correctly handle return value from queue_delayed_work()

From: Benjamin Romer <benjamin.romer@unisys.com>

commit f84bd6267d623b49f196d54ba9edc41ff1c4d5e3 upstream.

Properly handle the return value from queue_delayed_work() - it's a
bool, not an int, so using a less than comparison isn't appropriate.

This mistake was found by David Binderman <dcb314@hotmail.com>.

[arnd: the fix is from 4.4 but needed some minor fixup to adapt
 to context changes]
