drm/amdgpu: Fix lockdep false positive in amdgpu_lockdep_init

Move fs_reclaim_acquire() to before all lock acquisitions to eliminate
false positive circular locking dependency warning.

This is a 7.2-cycle regression fix suitable for stable backport.

v3: Address Mikhail Gavrilov technical review:
    - Clarify that fs_reclaim_acquire/release pair only REGISTERS the
      fs_reclaim lock class, does NOT create a static edge when called
      with no locks held
    - Explain that the actual fs_reclaim -> notifier_lock edge is
      established at runtime during memory reclaim -> MMU notifier path

v2: Address Mikhail Gavrilov review feedback:
    - Fix author name: Michael -> Mikhail Gavrilov in all trailers
    - Add Fixes: tag to link regression to original commit
    - Add Tested-by: Mikhail Gavrilov (tested on RX 7900 XTX)
