Subject: [PATCH net 1/7] ice: Fix entering Safe Mode

From: Marcin Szycik <marcin.szycik@...ux.intel.com>

If DDP package is missing or corrupted, the driver should enter Safe Mode.
Instead, an error is returned and probe fails.

To fix this, don't exit init if ice_init_ddp_config() returns an error.

Repro:
* Remove or rename DDP package (/lib/firmware/intel/ice/ddp/ice.pkg)
* Load ice

Fixes: cc5776fe1832 ("ice: Enable switching default Tx scheduler topology")
