9p: strlen() doesn't count the terminator
This is an off by one bug because strlen() doesn't count the NULL terminator. We strcpy() addr into a fixed length array of size UNIX_PATH_MAX later on. The addr variable is the name of the device being mounted. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
