Change subject: tbf_ul_fsm: Avoid freeing tbf after 4 CV=0 retrans in acknowledged mode
......................................................................
tbf_ul_fsm: Avoid freeing tbf after 4 CV=0 retrans in acknowledged mode
The restriction to only to transmit last data block (CV=0) up to 4 times
only applies in Unacknowledged mode of operation, which we don't
support. Hence, simply comment it out so that it can be enabled if
unacknowledge mode is ever supported.
