qcacld-3.0: Clear pending flag in hdd_destroy_acs_timer()

hdd_create_acs_timer() sets VENDOR_ACS_RESPONSE_PENDING, but
hdd_destroy_acs_timer() does not ensure this flag is cleared. This can
lead to a situation where the ACS timer is not initialized, but parts of
the code incorrectly assume that it is. Clear
VENDOR_ACS_RESPONSE_PENDING in hdd_destroy_acs_timer() to prevent
invalid access to the ACS timer.
