Subject: [PATCH] ath10k: htc: match wait_for_completion_timeout return type

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

CONFIG_ATH10K=m

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