net/sfc/base: fix manual filter delete in EF10

[ upstream commit 977424c ]

When user requests a filter deletion only filter with
manual priority must be deleted. When an automatic filter has
the same specification, it must be skipped.

Fixes: 585c22e ("net/sfc/base: handle manual and auto filter clashes in EF10")
