[PATCH] spi: fsl-quadspi: cleanup wait_for_completion return handling

[Nicholas Mc Guire]

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.

As the returnvalue of wait_for_completion_timeout is logically treated here
as a boolean (timeout occured or not) it can be wrapped into the if condition
directly and no additional variable is needed.

This patch was only compile tested with imx_v6_v7_defconfig
(implies CONFIG_SPI_FSL_QUADSPI=y)

Patch is against 3.19.0-rc6 -next-20150130
