return type of wait_for_completion_timeout is unsigned long not int, this
patch uses the return value of wait_for_completion_timeout in the condition
directly rather than adding a additional appropriately typed variable.

The return type of wait_for_completion_timeout is unsigned long not
int. This patch resolves the type mismatch by moving the call to
wait_for_completion_timeout into the condition.
This patch was only compile tested with mxs_defconfig
Patch is against 3.19.0-rc6 -next-20150130
