Subject: ice: remove VLAN representor specific ops
Patch-mainline: v6.0-rc1
Git-commit: b33de560f9e97a485ebc62dac9e0c0825cfdc731
References: jsc#PED-376

In switchdev mode VF VLAN caps will not be set there is no need
to have specific VLAN ops for representor that only returns not
supported error.

As VLAN configuration commands will be blocked, the VF driver
can't disable VLAN stripping at initialization. It leads to the
situation when VLAN stripping on VF VSI is on, but in kernel it
is off. To prevent this, disable VLAN stripping in VSI
initialization. It doesn't break other usecases, because it is set
according to kernel settings.
