Subject: Bluetooth: Ignore H5 non-link packets in non-active state
From: Loic Poulain <loic.poulain@xxxxxxxxx>
commit 48439d501e3d9e8634bdc0c418e066870039599d upstream.
When detecting a non-link packet, h5_reset_rx() frees the Rx skb.
Not returning after that will cause the upcoming h5_rx_payload()
call to dereference a now NULL Rx skb and trigger a kernel oops.
