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 assigning it to an incorrect type variable.

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

v2: fixed the broken indentation reported by Mark Brown <broonie@kernel.org>

This patch was only compile tested with omap2plus_defconfig
(implies CONFIG_SPI_TI_QSPI=m)

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