tracing/uprobes: Move argument fetching to uprobe_dispatcher()
...
A single uprobe event might serve different users like ftrace and
perf. And this is especially important for upcoming multi buffer
support. But in this case it'll fetch (same) data from userspace
multiple times. So move it to the beginning of the dispatcher
function and reuse it for each users.
