Avoid double free of _SPI_current->tuptable. AtEOSubXact_SPI() now tries to
release it in a subtransaction abort, but this neglects possibility thatsomeone outside SPI already did. Fix is for spi.c to forget about a tuptableas soon as it's handed it back to the caller.Per bug #2817 from Michael Andreen.
