User commands updated to handle channel request

User commands updated to handle channel request properly.
1. Self channel number 0xE will be converted properly as per
the interfaces
2. Will handle commands to set / get access for session based
channels only.

Unit-test:
Verfied get / set user access command works on self-channel
and session based channels accordingly. 0xCC will returned
for session-less channels
