[PATCH net 3/3] ice: Fix safe mode when DDP is missing

[Jacob Keller <jacob.e.keller@intel.com>]

From: Mateusz Pacuszka <mateuszx.pacuszka@intel.com>

One thing is broken in the safe mode, that is
ice_deinit_features() is being executed even
that ice_init_features() was not causing stack
trace during pci_unregister_driver().

Add check on the top of the function.

Fixes: 5b246e533d01 ("ice: split probe into smaller functions")
