ice: Refactor status flow for DDP load

Before this change, final state of the DDP pkg load process was
dependent on many variables such as: ice_status, pkg version,
ice_aq_err. The last one had be stored in hw->pkg_dwnld_status.
It was impossible to conclude this state just from ice_status, that's
why logging process of DDP pkg load in the caller was a little bit
complicated.

With this patch new status enum is introduced - ice_ddp_state.
It covers all the possible final states of the loading process.
What's tricky for ice_ddp_state is that not only
ICE_DDP_PKG_SUCCESS(=0) means that load was successful. Actually
three states mean that:
 - ICE_DDP_PKG_SUCCESS
 - ICE_DDP_PKG_SAME_VERSION_ALREADY_LOADED
 - ICE_DDP_PKG_COMPATIBLE_ALREADY_LOADED
ice_is_init_pkg_successful can tell that information.

One ddp_state should not be used outside of ice_init_pkg which is
ICE_DDP_PKG_ALREADY_LOADED. It is more generic, it is used in
ice_dwnld_cfg_bufs to see if pkg is already loaded. At this point
we can't use one of the specific one (SAME_VERSION, COMPATIBLE,
NOT_SUPPORTED) because we don't have information on the package
currently loaded in HW (we are before calling ice_get_pkg_info).

We can get rid of hw->pkg_dwnld_status because we are immediately
mapping aq errors to ice_ddp_state in ice_dwnld_cfg_bufs.

Other errors like ICE_ERR_NO_MEMORY, ICE_ERR_PARAM are mapped the
generic ICE_DDP_PKG_ERR.
