Eliminate some double-frees.

The cfile_ error-reporting routines free err_info; the caller doesn't
have to and, in fact, mustn't do so themselves.

While we're at it, make sure wtap_seek_read() always zeroes out *err and
nulls out *err_info, so the latter either points to a freshly-allocated
string or is null.
