target/i386/monitor: Propagate CPU address space to 'info mem' handlers

We want to replace the cpu_physical_memory_read() calls by
address_space_read() equivalents. Since the latter requires
an address space, and these commands are run in the context
of a vCPU, propagate its first address space. Next commit
will do the replacements.
