Remove a couple of unnecessary if-tests.

Commit abd9ca377 replaced a couple of while-loops in fmtfloat()
with calls to dopr_outchmulti, but I (tgl) failed to notice that
the new if-tests guarding those calls were really unnecessary,
because they're inside a larger if-block checking the same thing.
