Bluetooth: bnep: fix wild-memory-access in proto_unregister

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: bnep: fix wild-memory-access in proto_unregister

There's issue as follows:
  KASAN: maybe wild-memory-access in range [0xdead...108-0xdead...10f]
  CPU: 3 UID: 0 PID: 2805 Comm: rmmod Tainted: G        W
  RIP: 0010:proto_unregister+0xee/0x400
  Call Trace:
   <TASK>
   __do_sys_delete_module+0x318/0x580
   do_syscall_64+0xc1/0x1d0
   entry_SYSCALL_64_after_hwframe+0x77/0x7f

As bnep_init() ignore bnep_sock_init()'s return value, and bnep_sock_init()
will cleanup all resource. Then when remove bnep module will call
bnep_sock_cleanup() to cleanup sock's resource.
To solve above issue just return bnep_sock_init()'s return value in
bnep_exit().
