af_unix: fix struct pid memory leak
Dmitry reported a struct pid leak detected by a syzkaller program.
Bug happens in unix_stream_recvmsg() when we break the loop when a
signal is pending, without properly releasing scm.
Fixes: b3ca9b02b007 ("net: fix multithreaded signal handling in unix recv routines")
