qcacld-3.0: Fix implicit declaration of function ‘cdp_register_pause_cb’

The header where cdp_register_pause_cb is defined was mistakenly
included under a FEATURE_WLAN_CH_AVOID feature guard. This caused
compilation issues when FEATURE_WLAN_CH_AVOID was not defined. Move the
include out of the feature guard.
