cobalt/posix/io: Remove unneeded special case of select_bind_one

Already at the time of introduction (8ac3db81

), -ENOENT was not
returned by any sane function behind rtdm_fd_select(). Today
rtdm_fd_select() officially only returns -EBADF or -EINVAL. By now it
also returns -EADV, via rtdm_fd_get() or a default select handler. The
only remaining possibility for -ENOENT is a select handler. In-tree,
a4l_rt_select actually has such a case, but for no sane reason this or
any out-of-tree driver case should receive special handling here.

Remove this case, these is also no need for the select_bind_one wrapper
