heap_prepare_freeze_tuple: Simplify coding
Commit d2599ecfcc74 introduced some contorted, confused code around:
readers would think that it's possible for HeapTupleHeaderGetXmin return
a non-frozen value for some frozen tuples, which would be disastrous.
There's no actual bug, but it seems better to make it clearer.
Per gripe from Tom Lane and Andres Freund.
