Bluetooth: cmtp: fix possible panic when cmtp_init_sockets() fails
[ Upstream commit 2a7ca7459d905febf519163bd9e3eed894de6bb7 ]
I got a kernel BUG report when doing fault injection test:
------------[ cut here ]------------
kernel BUG at lib/list_debug.c:45!
...
RIP: 0010:__list_del_entry_valid.cold+0x12/0x4d
...
Call Trace:
proto_unregister+0x83/0x220
cmtp_cleanup_sockets+0x37/0x40 [cmtp]
cmtp_exit+0xe/0x1f [cmtp]
do_syscall_64+0x35/0xb0
entry_SYSCALL_64_after_hwframe+0x44/0xae
If cmtp_init_sockets() in cmtp_init() fails, cmtp_init() still returns
success. This will cause a kernel bug when accessing uncreated ctmp
related data when the module exits.
