udev: add --no-devices option for calling 'mdadm --detail'
When creating symlink of a md raid device, the detailed information of
component disks are unnecessary for rule udev-md-raid-arrays.rules. For
md raid devices with huge number of component disks (e.g. 1500 DASD
disks), the detail information of component devices can be very large
and exceed udev monitor's on-stack message buffer.
This patch adds '--no-devices' option when calling mdadm by,
IMPORT{program}="BINDIR/mdadm --detail --no-devices --export $devnode"
Now the detailed output won't include component disks information,
and the error message "invalid message length" reported by systemd can
be removed.
