fuse: fix copy_file_range() in the writeback case
commit a2bc92362941006830afa3dfad6caec1f99acbf5 upstream.
Prior to sending COPY_FILE_RANGE to userspace filesystem, we must flush all
dirty pages in both the source and destination files.
This patch adds the missing flush of the source file.
Tested on libfuse-3.5.0 with:
libfuse/example/passthrough_ll /mnt/fuse/ -o writeback
libfuse/test/test_syscalls /mnt/fuse/tmp/test
Fixes: 88bc7d5097a1 ("fuse: add support for copy_file_range()")
