[PATCH] ath9k: match wait_for_completion_timeout return type

[Nicholas Mc Guire]

Return type of wait_for_completion_timeout is unsigned long not int.
As time_left is exclusively used for wait_for_completion_timeout here its
type is simply changed to unsigned long.

API conformance testing for completions with coccinelle spatches are being
used to locate API usage inconsistencies:
./drivers/net/wireless/ath/ath9k/link.c:197
        int return assigned to unsigned long

Patch was compile tested with x86_64_defconfig + CONFIG_ATH_CARDS=m,

Patch is against 4.1-rc3 (localversion-next is -next-20150514)
