[PATCH 6.1 154/609] net: stmmac: reset residual action in L3L4 filters on delete

6.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nazim Amirul <[email protected]>

[ Upstream commit a448f821289934b961dd9d8d0beb006cc8937ba2 ]

When deleting an L3/L4 flower filter entry, the action field is not
reset. If a filter was previously configured with a drop action, that
action may persist and affect subsequent filter configurations
unintentionally.

Clear the action field when the filter entry is deleted.

Fixes: 425eabddaf0f ("net: stmmac: Implement L3/L4 Filters using TC Flower")
