Murphy Zhou 4f6c9caf7b ovl: add splice file read write helper
[ Upstream commit 1a980b8cbf0059a5308eea61522f232fd03002e2 ]

Now overlayfs falls back to use default file splice read
and write, which is not compatiple with overlayfs, returning
EFAULT. xfstests generic/591 can reproduce part of this.

Tested this patch with xfstests auto group tests.
