[PATCH] ath10k: htc: match wait_for_completion_timeout return type

[Nicholas Mc Guire <hofrat@osadl.org>]

Return type of wait_for_completion_timeout is unsigned long not int.
An appropriately named unsigned long is added and the assignments fixed up.

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

Patch was only compile tested with x86_64_defconfig + CONFIG_ATH_CARDS=m,
CONFIG_ATH10K=m

Patch is against 4.0-rc3 (localversion-next is -next-20150313)
