commit a35d8f016e0b68634035217d06d1c53863456b50 upstream.
Since 5.10, splice() or sendfile() to NILFS2 return EINVAL. This was
caused by commit 36e2c7421f02 ("fs: don't allow splice read/write
without explicit ops").
This patch initializes the splice_write field in file_operations, like
most file systems do, to restore the functionality.
