sema: rescue entries anywhere in a pushbuffer slot
Mid-slot entry VAs were rejected by the alignment guard, leaving their
false translations permanent. Candidate 2 (the group's page minus the
push length) is the PA of the entry VA's page regardless of alignment;
pin only the pages the push occupies for mid-slot entries and the whole
1 MB slot for slot-aligned ones. Validation by read-back is unchanged.
