[lc_ctrl] Fix for unconnected WE checker on tap side
[lc_ctrl] Fix for unconnected WE checker on tap side

This integrity error remained unconnected because initially the reg_top
only checked for bus integrity errors (and the TAP side does not support
that). However, since we now also have WE checkers inside the reg_top,
this signal should be connected for the TAP side also.
