sfc: Allow filter removal only with exactly matching priority
Currently a higher priority client can remove a lower priority
client's filter with equal match-expression. This might happen if (a)
the higher priority client has a double-free bug, or (b) another
client with sufficient priority replaced and then removed an equal
filter, allowing the low priority client to insert an equal filter.
In neither case does it actually make sense to carry out the removal;
we should say the filter doesn't exist, as the filter currently
present is not the one that the high-priority client is referring to.
