Michael Paquier 1f8ab91c11 amcheck: Fix memory leak with gin_index_check() ...

"prev_tuple" was overwritten with a new tuple coming from
CopyIndexTuple() on each loop, leaking memory for every tuple processed
on entry tree pages.  The function uses a dedicated memory context, but
this could leave unused large areas of memory while processing a large
GIN index, the larger the worse.

Oversight in 14ffaece0f.
