return type of wait_for_completion_timeout is unsigned long not int, rather
than introducing a new variable the wait_for_completion_timeout is moved
into the if condition as the return value is only used to detect timeout.

Aside from the fixup of the wait_for_completion_timeout handling
a minor coding style issue in the else branch was fixed - the {} is
not needed for the one-line body.
Patch was compile tested only for imx_v6_v7_defconfig + CONFIG_IIO=m
CONFIG_STAGING=y, CONFIG_AD7780=m, CONFIG_AD_SIGMA_DELTA=m
Patch is against 3.19.0-rc6 -next-20150130
