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

This patch initiates 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.
