[Impact]
lock_sock on bt_sock_recvmsg() from net/bluetooth/af_bluetooth.c
may cause a deadlock.

[Backport]
Due to the lack of f4b41f062c42 ("net: remove noblock parameter from
skb_recv_datagram()"), Jammy and Focal had a small context conflict.
Focal also had another context conflict due to it not having
b8ddc3b14c7a ("Bluetooth: fix indentation and alignment reported by
checkpatch").

[Test]
Compile tested.

[Where problems could occur]
Any issues here would direcly impact Bluetooth usage.

[Other info]
This is also a follow-up fix to CVE-2023-51779.
