sctp: fix memory leak in sctp_stream_outq_migrate() ...
[ Upstream commit 9ed7bfc79542119ac0a9e1ce8a2a5285e43433e9 ]
When sctp_stream_outq_migrate() is called to release stream out resources,
the memory pointed to by prio_head in stream out is not released.
The memory leak information is as follows:
unreferenced object 0xffff88801fe79f80 (size 64):
comm "sctp_repo", pid 7957, jiffies 4294951704 (age 36.480s)
hex dump (first 32 bytes):
