tty: vt: remove checks for count in consw::con_clear() implementations
'count' in consw::con_clear() is guaranteed to be positive. csi_X() (the
only caller) takes the minimum of the vc parameter (which is at least 1)
and count of characters till the end of the line. The latter is computed
as a subtraction of vc->vc_cols (count) and vc->state.x (offset). So for
the worst case, full line, it is 1.
Therefore, there is no point in checking zero or negative values (width
is now unsigned anyway).
