PS4:
I am fine with getting this patch merged, since it makes the code cleaner. But still hoping to see the formatting issues being addressed in a follow up patch.

Change subject: WIP: Assume MultiSlot Class 1 if unknown
......................................................................
WIP: Assume MultiSlot Class 1 if unknown
Until now, if timeslot resources where being allocated for an MS for
which its msclass is not known, msclass=12 was being selected.
While it's true that msclass=12 is quite a usual one implemented by
phones (Rx=4, Rx=4, Sum=5), some MS implementations may not support such
modes.
As a result, if the PCU allocates a TBF for an MS which its msclass is
not known (eg. because it used 1-phase access aka no Pkt Res Req), then
a minimal msclass=1 must be assumed. Otherwise, it may assign more
multislots than the MS can handle, and will work incorrectly since an
amount of RLC/MAC blocks won't be sent/received properly.
