Wang Hai d2e7a4d20f Bluetooth: cmtp: fix possible panic when cmtp_init_sockets() fails
[ Upstream commit 2a7ca7459d ]

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.
