Subject: [PATCH] ice: Fix double VLAN error when entering promisc mode

Avoid enabling or disabling VLAN 0 when trying to set promiscuous VLAN mode if double VLAN mode is enabled. This fix is needed because the driver tries to add the VLAN 0 filter twice (once for inner and once for outer) when double VLAN mode is enabled. The filter program is rejected by the firmware when double VLAN is enabled, because the promiscuous filter only needs to be set once.

This issue was missed in the initial implementation of double VLAN mode.
