net: strparser: fix skb_head leak in strp_abort_strp()

In the Linux kernel, the following vulnerability has been resolved:

net: strparser: fix skb_head leak in strp_abort_strp()

When the stream parser is aborted, for example after a message assembly timeout,
it can still hold a reference to a partially assembled message in
strp->skb_head.

That skb is not released in strp_abort_strp(), which leaks the partially
assembled message and can be triggered repeatedly to exhaust memory.

Fix this by freeing strp->skb_head and resetting the parser state in the
abort path. Leave strp_stop() unchanged so final cleanup still happens in
strp_done() after the work and timer have been synchronized.
