xfs: untangle the open zones reporting in mountinfo

Browse Source 
Keeping a value per line makes parsing much easier, so move the maximum
number of open zones into a separate line, and also add a new line for
the number of open open GC zones.  While that has to be either 0 or 1
currently having a value future-proofs the interface for adding more open
GC zones if needed.
