Reconstruct new packet to accomodate extra header length

Use case: Bluetooth process crash problem in the middle of RFCOMM
test cases due to buffer corruption detected while freeing it.

Root Cause: RFCOMM layer trying to reuse the same packet to send
to the lower layer but it will fail due to strick buffer
corruption checks.

Failure: Bluetooth process crash.

Fix:  created a new packet to accomadate new header
and copied the same payload to the new packet.
