The FD_PREPARE() cleanup class allocated and installed immediately and required fd_publish() to be the last thing that could fail. Reimplement it on the deferred path. FD_PREPARE() reserves a slot with fd_prepare() and stages the file on it. The syscall exit installs on success and drops on error. fd_prepare_fd() and fd_prepare_file() now read the slot. fd_publish() is gone. Convert every FD_PREPARE() user since fdf.err can now become a simple IS_ERR(fdf). Signed-off-by: Christian Brauner (Amutable) <brauner@kernel.org>
