Subject: [PATCH net-next] net: strparser: fix strparser sk_user_data check

sk_user_data mismatch between what kcm expects (psock) and what strparser expects (strparser).

Queued rx_work, for example calling strp_check_rcv after socket buffer changes, will never complete.

sk_user_data is unused in strparser, so just remove the check.
