lock_move_reorganize_page() early exit check is useful only with lock elision

After MDEV-40128, the early exit check in lock_move_reorganize_page() is useful only with lock elision support.
This is because, when lock elision is not supported, TMLockGuard falls back to behave like LockGuard.
The same check would be done using LockGuard later, in any case.
Hence, the early exit check can be skipped when lock elision is not supported.
