Subject: [PATCH] net/i40e: fix DDP profile DEL operation

[ upstream commit 0585f5c3d2643e49c0d2629e4937fb0bf010afbd ]

Customized info will be updated when processing DDP package,
including PCYPE/PTYPE/protocol. Previously, the customized info
is updated without any check for package operation - ADD or DEL,
but only covers ADD operation. In this situation, even if a package
is being removed, new PCTYPE/PTYPE/protocol will still be created,
it will cause wrong parsing for SW. This patch cleans new
PCTYPE/PTYPE/protocol created when a package is being removed.

Fixes: e163c18a15b0 ("net/i40e: update ptype and pctype info")
