Different issue, and I'm not sure why that WARN_ON() is there in the
first place.  Note that in a similar situation generic_file_direct_write()
simply buggers off and lets the caller do buffered write...

iov_iter_pipe() warning is a sign of ->read_iter() on pipe-backed iov_iter
putting into the pipe more than it claims to have done.
