disc: log adaptive patch speed transitions; issue SET CD SPEED max unconditionally

Two recovery-path fixes:
- patch: log the per-range speed transitions (INFO, phase="patch_speed") — each
  range enters at 0xFFFF (max) and drops to 0x0000 (slow recovery) on its first
  read failure. Previously the adaptive-speed behavior was invisible in the logs.
- drive init: issue the generic SET CD SPEED max UNCONDITIONALLY at drive-open,
  not only when a firmware unlocker matched. A stock-mode BD/UHD drive (no
  firmware unlock) was left riplocked because the call sat inside the
  unlocker-matched branch.
