[dpdk-stable] [PATCH] net/sfc/base: fix manual filter delete in EF10

[Andrew Rybchenko]

From: Igor Romanov <igor.romanov at oktetlabs.ru>

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: 585c22edb29c ("net/sfc/base: handle manual and auto filter clashes in EF10")
