Remove unneeded nbtree latestRemovedXid comments.

Discussing the low level issue of nbtree VACUUM and recovery conflicts
in btvacuumpage() now seems inappropriate.  The same issue is discussed
in nbtxlog.h, as well as in a comment block above _bt_delitems_vacuum().

The comment block made more sense when it was part of a broader
discussion of nbtree VACUUM "pin scans".  These were removed by commit
9f83468b.
