tbf: Clean up gprs_rlcmac_dl_tbf::handle()

Avoid passing tons of params to internal helper function
tbf_nel_dl_assignment() in order to either fetch again the ms object or
create a new one. Let's instead create the ms function earlier if needed
and fill it with all the discovered information prior to calling the
helper function. This provides cleaner code and also better log output.

This way we also avoid trying to fill the MS twice and unneeded
getter+setter for TA.

tbf::imsi(): There' always an ms, so simply forward call to
ms()->imsi().

We can also get rid of assign_imsi, since the modified code is the only
place where it's used and there's already some code in place there to
update the MS. We instead merge it with set_imsi and keep the
duplication code to catch possible bugs from callers.

Move merge_and_clear_ms from tbf class to GprsMS, where it really
belongs.
