mdopen: call "modprobe md_mod" if it might be needed.
Creating an array by opening a block-device with major number of 9
will transparently load the md module if needed.
Creating an array by opening
/sys/module/md_mod/parameters/new_array
and writing to it won't, it will just fail if md_mod isn't loaded.
So when opening that file fails with ENOENT, run "modprobe md_mod" and
try again.
This fixes a bug whereby if you have "CREATE names=yes" in mdadm.conf,
and the md modules isn't loaded, then creating or assembling an
array will not honor the "names=yes" configuration.
