Source kernel commit: 1d319ac6fe1bd6364c5fc6e285ac47b117aed117

Zoned file systems not only don't use the global frextents counter, but
for them the in-memory percpu counter also includes reservations taken
before even allocating delalloc extent records, so it will never match
the per-zone used information.  Disable all updates and verification of
the sb counter for zoned file systems as it isn't useful for them.
