[PATCH 5.1 20/98] net: mvpp2: prs: Use the correct helpers when removing all VID filters

[Greg Kroah-Hartman]

From: Maxime Chevallier <maxime.chevallier@xxxxxxxxxxx>

[ Upstream commit 6b7a3430c163455cf8a514d636bda52b04654972 ]

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")
