Dont warn when DM_DEV_REMOVE ioctl is tried on a open device.
On openSUSE when cryptsetup and udev interact, cryptsetup sometimes tries to
remove a dm device currently opened by blkid, which is not a serious issue to
print a kernel warning. The application should retry if -EBUSY is returned. So
let us make it an informational message instead.
