Revert "btrfs: add ioctl to export size of global metadata reservation"

Browse source 
This reverts commit 01e219e806.

David Sterba found a different way to provide these features without adding a new
ioctl.  We haven't released any progs with this ioctl yet, so I'm taking this out
for now until we finalize things.
