sema: add walk_probe - trace the page-table walk for a VA
New module parameter walk_probe <va> runs the recorded-va-space walks and
the discovered-directory walk directly (pin/lat/pair map bypassed) with
per-level tracing, and prints the result of each. This separates 'the
page tables are not walkable' from 'the VA->PA pair map already answers'
when a translation is missing. Baseline on a live boot: root PDB entries
are zero (L0 e=0 idx=0) so the writes UVM issues into the level pages
have no parent entry yet.
