carl9170: 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
as well as error checking fixed up.
API conformance testing for completions with coccinelle spatches are being
used to locate API usage inconsistencies:
./drivers/net/wireless/ath/carl9170/usb.c:675
int return assigned to unsigned long
Patch was compile tested with x86_64_defconfig + CONFIG_ATH_CARDS=m,
CONFIG_CARL9170=m
Patch is against 4.1-rc3 (localversion-next is -next-20150512)
