BUGS: btrfs multi-device support fixes

[Gene Czarcinski]

There are two patches needed in grub2 to support multi-device btrfs volumes.

This first patch (previously submitted) involves the parameters passed 
to grub2-probe.  If not correctly passed, grub2-probe issues an error 
message.  The related problem report is:
  https://bugzilla.redhat.com/show_bug.cgi?id=890955

The second problem involves having a multi-device btrfs volume with 
/boot being on the btrfs volume either as part of the root subvolume or 
as a separate subvolume.  The result is an error messare at boot time:
    error: no such device: root.
    hit any key to continue

The solution is to modify grub-probe.c so that " " is issued rather than 
"\n" for a hint.   The related problem report is:
  https://bugzilla.redhat.com/show_bug.cgi?id=1023161

To minimize problems, the two patches have been attached rather than 
provided inline.

Peter, I cc'ed you so you would be aware of these bug reports.  It would 
be nice if this was applied to both Fedora 20 and 19.
