Delete the redundant tbl span flags, just inspect the actual data
where needed, which is less fragile.
This fixes a subtle NULL pointer access to tp->tbl.cols:
Due to a bug in the man(7) parser, the first span of a table can
end up in a .TP head, in which case tblcalc() was never called.
Found by jsg@ with afl.
