Chan Shu Tak, Alex 5485d62cf5 llc2: Fix return statement of llc_stat_ev_rx_null_dsap_xid_c (and _test_c) 
[ Upstream commit af1c0e4e00f3cc76cb136ebf2e2c04e8b6446285 ]

When a frame with NULL DSAP is received, llc_station_rcv is called.
In turn, llc_stat_ev_rx_null_dsap_xid_c is called to check if it is a NULL
XID frame. The return statement of llc_stat_ev_rx_null_dsap_xid_c returns 1
when the incoming frame is not a NULL XID frame and 0 otherwise. Hence, a
NULL XID response is returned unexpectedly, e.g. when the incoming frame is
a NULL TEST command.

To fix the error, simply remove the conditional operator.

A similar error in llc_stat_ev_rx_null_dsap_test_c is also fixed.
