Bluetooth: Call iso_exit() on module unload
If iso_init() has been called, iso_exit() must be called on module
unload. Without that, the struct proto that iso_init() registered with
proto_register() becomes invalid, which could cause unpredictable
problems later. In my case, with CONFIG_LIST_HARDENED and
CONFIG_BUG_ON_DATA_CORRUPTION enabled, loading the module again usually
triggers this BUG():
list_add corruption. next->prev should be prev (ffffffffb5355fd0),
but was 0000000000000068. (next=ffffffffc0a010d0).
