[OpenWrt-Devel] [PATCH Request][rpcd] file: add reply to write function

[Lazar Demin]

This patch adds a reply to the file write ubus call:
{
"code": 0,
"bytes": 9
}

Where code is the return code of the operation and bytes is the number of
bytes written.

Getting a response is helpful since it lets the user know if the write
operation was successful, knowing the number of bytes written allows for
further error checking.

Can this patch be merged into the rpcd repo?
