[PATCH_v7 3/5] bnep: Add bnep_disconnect and bnep_set_disconnect apis

[Ravi kumar Veeramally <ravikumar.veeramally@linux.intel.com>]

Set disconnect call and callback will be triggered by I/O event on
bnep channel. Call bnep_disconnect, it will delete bnep connection
and down the interface, if interface is not up and running do not
use this api, simply call bnep_free.
