Subject: [PATCH] [bluetooth] fix compile error in dbus fake bluetooth device client

This fixes a compile error that was accidentally introduced in
https://crrev.com/2191232. For unknown reasons this does not cause a
compile error with libc++, which is normally used with chromium, but
does cause an error with stdlibc++.

The API for preparing write requests was not changed in
https://crrev.com/2191232, so the change that introduced this error
was incorrect anyway. This reverts the change that introduced the
error and adds the kTypeRequest argument to the call to WriteValue()
since that was the API that was actually changed in the prior CL.

Bug: 1092470
Change-Id: I6f6fe90ab42aea3db8cac95b69aee5095ea33b31
