Fix in file qemu-sockets.c

1) Changed usage of malloc,free,strdup to qemu_malloc,qemu_free,qemu_strdup 2) Some coding style fixes (based on CODING_STYLE document) 3) Free struct addrinfo *res after failure of listen Signed-off-by: vibi <vibi_sreenivasan@cms.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
