block: handle huge zero folios in bio_free_folios
When CONFIG_PERSISTENT_HUGE_ZERO_FOLIO is enabled, iomap_dio_zero() can
add a huge zero folio to a zeroing bio, which needs special treatment
in bio_free_folios by also checking is_huge_zero_folio() in addition to
is_zero_folio().
Fixes: 8dd5e7c75d7b ("block: add helpers to bounce buffer an iov_iter into bios")
