Async read and write go synchronous in the same case,
so do the same here.

In all places where we access or modify a file or it's associated metadata, we
use fsp_get_io_fd() to fetch the low-level fd from the fsp. This ensures we
don't accidentally use a pathref fsp where the fd would be opened as root on
systems lacking O_PATH.

Since this was written, our write path has changed significantly. In
particular we have gained very flexible support for async I/O, with the
linux io_uring in the pipeline. Caching stuff in main memory and then
doing a blocking pwrite nowadays does not belong into the core smbd
code. If someone wants it back, it should be doable in a VFS module.
Removes: "write cache size" parameter.

SMB2 FLUSH mainly calls fsync and there is already code in place to
handle fsync asynchronously, so use the asynchronous code path for SMB2
FLUSH. This avoids a SMB2 FLUSH stalling other requests processing.

It turns out that the persistent handles are used by the Microsoft
redirector to index files on oplock break requests. So even if we
don't do durable handles (yet) we must set the persistent handle
on create. For now just use the same handle value as we use for
volatile.
