edge: Move EGPRS setup from setup_tbf to tbf_alloc_ul_tbf

Currently the EGPRS mode is enabled in setup_tbf depending on the
values of egprs_ms_class and bts->egprs_enabled (both must be != 0).
This makes it difficult to set different values (like window
parameters) depending on the direction.

This commit moved the initialisation part to tbf_alloc_ul_tbf und
just leaves the setting of the ms_class to setup_tbf.
