rlcmac: tbf_ul: Fix wrong field assignment (no bug in practice)

Fixes following warning detected by clang:
"""
tbf_ul.c:1118:37: warning: implicit conversion from enumeration type
'enum gprs_rlcmac_rlc_egprs_ul_reseg_bsn_state' to different enumeration type
'enum gprs_rlcmac_rlc_egprs_dl_reseg_bsn_state' [-Wenum-conversion]
blk->spb_status.block_status_dl = reseg_status;
"""

In practice it's not much of a problem since both fields are put
together in a union, so it ends up in the same place in memory.
