Boris Burkov de95dd6b4d btrfs: fix folio refcount in __alloc_dummy_extent_buffer() 
commit a56c85fa2d59ab0780514741550edf87989a66e9 upstream.

Another improper use of __folio_put() in an error path after freshly
allocating pages/folios which returns them with the refcount initialized
to 1. The refactor from __free_pages() -> __folio_put() (instead of
folio_put) removed a refcount decrement found in __free_pages() and
folio_put but absent from __folio_put().

Fixes: 13df3775efca ("btrfs: cleanup metadata page pointer usage")
