OPP: Remove sdp record during BT off to prevent leak

Step by Step procedure:
===================
1. DO file transfer using OPP.
2. Turn off BT.
3. Turn on BT.
4. Repeat above 4 steps for multiple times.

Expected Result:
================
File transfer should get success.

Actual Result:
==============
Instead of OPP request, observed MAP authentication dialog popped up.

Reproducibility:
==============
very rare

Root cause:
===========
There is a leak in security manager record even though socket is closed.
AS there could be two entries with same PSM ( one for MAP and other for OPP ),
when there is an incoming connection for OPP, it may take MAP entry as it is first
and goes ahead with high security which is not expected.

Fix:
====
Assign proper value to SDP handle to remove SDP record created dynamically
for OPP server during off state. without this call, there is a leak in sdp
layer in the stack as sdp record is never removed, even though socket is closed.

Test: Checked above use-case and no error is seen.
