Subject: ice: Treat DCBx state NOT_STARTED as valid
Patch-mainline: v5.4-rc1
Git-commit: 64bcaec64284e08430db5f00944443ec41a86df2
References: jsc#SLE-7926

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.
