Mateusz Guzik b97a758ffc filedesc: tidy up fdcopy a little bit
Test for file availability by fde_file != NULL instead of fdisused, this is
consistent with similar checks later.

Drop badfileops check. badfileops don't have DFLAG_PASSABLE set, so it was never
reached in practice.

fdiused is now only used in some KASSERTS, so ifdef it under INVARIANTS.

No functional changes.
