can: j1939: transport: j1939_session_skb_drop_old(): spin_unlock_irqrestore() before kfree_skb()

stable inclusion
from stable-v5.10.153
commit 370be31cde501179b7c7a295732b0105274b3f58
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I64YCA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=370be31cde501179b7c7a295732b0105274b3f58



--------------------------------

commit c3c06c61 upstream.

It is not allowed to call kfree_skb() from hardware interrupt context
or with interrupts being disabled. The skb is unlinked from the queue,
so it can be freed after spin_unlock_irqrestore().

Fixes: 9d71dd0c ("can: add support of SAE J1939 protocol")
