l2cap_ecred_reconf_rsp() calls l2cap_chan_del() without holding l2cap_chan_lock(). Every other l2cap_chan_del() caller in the file acquires the lock first. A remote BLE device can send a crafted L2CAP ECRED reconfiguration response to corrupt the channel list while another thread is iterating it. Add l2cap_chan_hold() and l2cap_chan_lock() before l2cap_chan_del(), and l2cap_chan_unlock() and l2cap_chan_put() after, matching the pattern used in l2cap_ecred_conn_rsp() and l2cap_conn_del().

Add an event filter to filter event with specific opcode to prevent BT stack from receiving unexpected event. Event with opcode 0xfc5d is generated when MediaTek's Bluetooth enable firmware logs and is not expected to be sent to userspace. Signed-off-by: Chris Lu <chris.lu@mediatek.com>

Add an event filter to filter event with specific opcode to prevent BT
stack from receiving unexpected event.
Event with opcode 0xfc5d is generated when MediaTek's Bluetooth enable
firmware logs and is not expected to be sent to userspace.
