return type of wait_for_completion_timeout is unsigned long not int, this
patch only fixes up the return handling.

Rather than changing timeout to unsigned long it can be moved into the
if condition and dropped.
Patch was compile tested only for imx_v6_v7_defconfig + CONFIG_IIO=m,
CONFIG_VF610_ADC=m
Patch is against 3.19.0-rc6 -next-20150130
