[PATCH net 2/2] net: mvpp2: prs: Use the correct helpers when removing all VID filters

[Maxime Chevallier]

When removing all VID filters, the mvpp2_prs_vid_entry_remove would be
called with the TCAM id incorrectly used as a VID, causing the wrong
TCAM entries to be invalidated.

Fix this by directly invalidating entries in the VID range.
