[ Upstream commit c8dc3047c48540183744f959412d44b08c5435e1 ]

We need to unmap pages from userspace process before removing pagecache
in punch_hole() like we did in f2fs_setattr().

Similar change:
commit 5e44f8c374dc ("ext4: hole-punch use truncate_pagecache_range")

Fixes: fbfa2cc58d53 ("f2fs: add file operations")
