Fix unsafe coding in ReorderBufferCommit().
"iterstate" must be marked volatile since it's changed inside the PG_TRY
block and then used in the PG_CATCH stanza. Noted by Mark Wilding of
Salesforce. (We really need to see if we can't get the C compiler to warn
about this.)
Also, reset iterstate to NULL after the mainline ReorderBufferIterTXNFinish
call, to ensure the PG_CATCH block doesn't try to do that a second time.
