Subject: [PATCH 304/359] mdopen: Prevent overrunning the devname buffer when
 copying devnm into it for long md names.
References: bsc#1081910

Linux allows for 32 character device names. When using the maximum
size device name and also storing "/dev/", devname needs to be 37
character long to store the complete device name.
i.e. "/dev/md_abcdefghijklmnopqrstuvwxyz12\0"
