slirp: fix leak
Spotted by ASAN:
/x86_64/hmp/pc-0.12:
=================================================================
==22538==ERROR: LeakSanitizer: detected memory leaks
Direct leak of 224 byte(s) in 1 object(s) allocated from:
#0 0x7f0f63cdee60 in malloc (/lib64/libasan.so.3+0xc6e60)
#1 0x556f11ff32d7 in tcp_newtcpcb /home/elmarco/src/qemu/slirp/tcp_subr.c:250
#2 0x556f11fdb1d1 in tcp_listen /home/elmarco/src/qemu/slirp/socket.c:688
#3 0x556f11fca9d5 in slirp_add_hostfwd /home/elmarco/src/qemu/slirp/slirp.c:1052
#4 0x556f11f8db41 in slirp_hostfwd /home/elmarco/src/qemu/net/slirp.c:506
#5 0x556f11f8dd83 in hmp_hostfwd_add /home/elmarco/src/qemu/net/slirp.c:535
There might be a better way to fix this, but calling slirp tcp_close()
doesn't work.
