[PATCH 10/11] netfs: Fix comment about write-streaming avoidance

In netfs_perform_write(), there used to be a section in which
write-streaming was avoided if either the fd is open O_RDWR or fscaching is
enabled, but the former was removed as netfs_read_folio() can now fill in
the gaps rather then flushing, but the comment was not updated.

Fix the comment to match.

Fixes: eac38f8a2b85 ("netfs: Fix write streaming disablement if fd open O_RDWR")
