Commit 3cbdb0343022 ("ice: Add support for E830 DDP package segment")
incorrectly removed support for package download for packages without a
signature segment. These packages include the signature buffer inline
in the configurations buffers, and not in a signature segment.

Fix package download by providing download support for both packages
with (ice_download_pkg_with_sig_seg()) and without signature segment
(ice_download_pkg_without_sig_seg()).

Fixes: 3cbdb0343022 ("ice: Add support for E830 DDP package segment")

Changelog
v2->v3:
- correct Changelog version tag, add Closes, Tested-by and Reviewed-by.
  Remove unnecessary local variable initialization in ice_dwnld_cfg_bufs(),
  and unnecessary local variable in ice_download_pkg_without_sig_seg(),
v1->v2:
- correct Reported-by email address.
