[PATCH] mm: shmem: avoid repeated flush dcache in shmem_writepage()

[Kefeng Wang <wangkefeng.wang@huawei.com>]

The folio_zero_range() already flush dcache inside, so remove another
flush_dcache_folio() in shmem_writepage().

Fixes: f530ed0e2d01 ("shmem: convert shmem_writepage() to use a folio throughout")
