The return value of wait_for_completion_timeout is unsigned long,
as it is used here for wait_for_completion_timeout only the type
of commretval was changed to unsigned long.
As wait_for_completion_timeout does not return negative values
the commretval < 0 case is not reachable and can be removed.
This was only compile-tested for x86_64_defconfig + CONFIG_MMC=m,
CONFIG_MMC_VUB300=m
Patch is against 3.19.0-rc4 -next-20150116
