Subject: [PATCH_v7 4/5] bnep: Refactored bnep connect and disconnect calls

Refactored bnep connect and disconnect calls to simplify and
keeping bnep related functionality behind curtains.
bnep_connect calls takes care of bnep_setup until interface up
then connect callback will be called. Set disconnect callback
when connect call succeeds. bnep_disconnect should be
called only when iface is up/connected.

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

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.
