prima: Add debug code to rootcause command timeout issue.
when EXIT_BMPS is pending in activeList, it causes crash
with excess logging for RoamPending list. In this scenario
gTraceTbl has lost SME details due to other MTRACE commands.
Because of which, the issue is not rootcaused.
Add below changes to rootcause if the issue appears again:
1. print only first 5 commands from roamPendingList
2. Bug_on if the commandlist is full
3. Add MTRACE for PMC commands
