[Gujulan Elango, Hari Prasath (H.)]

simplified time_before() macro

	v2:Fixes a build warning.time_before() macro requires both of
its arguments to be unsigned long.Build warning was missed & later
reported by the kbuild test robot.Previous version of this patch was
sent with a wrong subject line i.e it was showing rtl8712e instead of
the rtl8192e.
