[PATCH] ath10k: mac: match wait_for_completion_timeout return type

[Nicholas Mc Guire]

Return type of wait_for_completion_timeout is unsigned long not int.
An appropriately named unsigned long is added, respectively 'ret'
renamed, and the assignments fixed up.

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)
