Subject: [PATCH] tracing/probes: Add fetch{,_size} member into deref fetch
 method

The deref fetch methods access a memory region but it assumes that
it's a kernel memory since uprobes does not support them.

Add ->fetch and ->fetch_size member in order to provide a proper
access methods for supporting uprobes.
