smbd: Remove write cache
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.
