[PATCH v1] obex: Fix the PBAP GET request in PTS testing

[Amisha Jain <quic_amisjain@xxxxxxxxxxx>]

This change is required for passing below PTS testcases:
1. PBAP/PSE/PBD/BV-02-C
2. PBAP/PSE/PBD/BV-03-C
3. PBAP/PSE/PBD/BI-01-C
4. PBAP/PSE/PBD/BV-13-C
5. PBAP/PSE/PBD/BV-14-C
6. PBAP/PSE/PBD/BV-17-C

PTS sends all the GET phonebook requests without extra params.
Therefore, the PBAP server is rejecting the requests with a
'Bad Request' response.
So append 'maxlistcount' as default param in GET request to
avoid testcase failure.
