fs: 9p: add generic splice_write file operation 

The default splice operations got removed recently, add it back to 9p
with iter_file_splice_write like many other filesystems do.

Link: http://lkml.kernel.org/r/1606837496-21717-1-git-send-email-asmadeus@codewreck.org


Fixes: 36e2c742 ("fs: don't allow splice read/write without explicit ops")
