OPP: Add checks to initiate rfcomm connection in case sdp fails

Initiate rfcomm connection directly when sdp fails to start
for Obex over l2cap. This would prevent usecases when in CTS
test multiple user are creted, and sdp is initiated by profile user
which is different from active user, resulting in unecessary wait
for 10 seconds for SDP, leading to test case failure.
