Subject: net: mvpp2: prs: Use the correct helpers when removing all VID
filters
Patch-mainline: v5.2-rc6
Git-commit: 6b7a3430c163455cf8a514d636bda52b04654972
References: bsc#1098633
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.
Fixes: 56beda3db602 ("net: mvpp2: Add hardware offloading for VLAN filtering")
