xfs: preserve owner on in-memory btree creation

Browse Source 
LOLLM points out a minor bug where a higher level function creating an
in-memory btree is required to pass in an owner number, but the creation
function erases that.  In-memory btrees are ephemeral so this really
doesn't matter except for debugging.  But let's fix this papercut.
