softmmu/physmem: Clean up local variable shadowing

Fix:

  softmmu/physmem.c: In function ‘cpu_physical_memory_snapshot_and_clear_dirty’:
  softmmu/physmem.c:916:27: warning: declaration of ‘offset’ shadows a parameter [-Wshadow=compatible-local]
    916 |             unsigned long offset = page % DIRTY_MEMORY_BLOCK_SIZE;
        |                           ^~~~~~
  softmmu/physmem.c:892:31: note: shadowed declaration is here
    892 |     (MemoryRegion *mr, hwaddr offset, hwaddr length, unsigned client)
        |                        ~~~~~~~^~~~~~
