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.

Signed-off-by: Nicholas Mc Guire <hofrat@osadl.org>

v2: fixup my slightly brain-dead indentation as suggested by Mark Brown 
    <broonie@kernel.org>.

This patch was only compile tested with mxs_defconfig
(implies CONFIG_SPI_MXS=y)

Patch is against 3.19.0-rc7 (localversion-next is -next-20150204)
