OpenWrt/Atheros: Fix detecting Atheros driver type for openwrt

When Radio is of type Offload, /sys/module/ath_hal entry is not
available due to recent division of HOST changes for Direct-Attach and
Offload code. So to check for openwrt_driver_type, verify umac driver
name, entry in "/sys/module/umac" than "/sys/module/ath_hal". That entry
is available for both cases.
