Subject: [PATCH 0/4] ath10k: a few incorrect return handling fix-up

wait_for_completion_timeout does not return negative values so the tests
for <= 0 are not needed and the case differentiation in the error handling
path unnecessary.

patch was only compile tested x86_64_defconfig + CONFIG_ATH_CARDS=m
CONFIG_ATH10K=m

patch is against linux-next 3.19.0-rc1 -next-20141226

None of the proposed cleanups are critical.
All changes should only be removing unreachable cases.
