net/ice/base: fix DCBx initialization

Browse Source 
When a port is not cabled, but DCBx is enabled in the firmware, the
status of DCBx will be NOT_STARTED. This is a valid state for FW
enabled and should not be treated as a is_fw_lldp true automatically.

Add the code to treat NOT_STARTED as another valid state.
