xfstest generic/074 and generic/075 complain result in kernel warning messages / page dumps. This is easily reproducible (on 6.19) with CONFIG_TRANSPARENT_HUGEPAGE_SHMEM_HUGE_ALWAYS=y CONFIG_TRANSPARENT_HUGEPAGE_TMPFS_HUGE_ALWAYS=y

This just adds a test for large folios fuse_try_move_folio with the same page copy fallback, but to avoid the warnings from fuse_check_folio().
