[PATCH 1/2 v3] spi: tegra20-sflash: cleanup wait_for_completion return handling

[Nicholas Mc Guire <hofrat@xxxxxxxxx>]

return type of wait_for_completion_timeout is unsigned long not int, this
patch adds an appropriate variable and fixes up the assignment.
As the string in dev_err already states "timeout" there
is little point in printing the 0 here.

v2: typo fixed as suggested by Laxman Dewangan <ldewangan@xxxxxxxxxx>
v3: merged dev_err into one line as suggested by Laxman Dewangan 
    <ldewangan@xxxxxxxxxx>

This patch was only compile tested with tegra_defconfig
(implies CONFIG_SPI_TEGRA20_SFLASH=y)

Patch is against 3.19.0-rc6 -next-20150202
