The ginfast.c code previously checked for conflicts in before locking the relevant buffer, leaving a window where a RW conflict could be missed. Re-order. There was also a place where buffer ID and block number were confused while trying to predicate-lock a page, noted by visual inspection. Back-patch to all supported releases. Fixes one more problem discovered with the reproducer from bug #17949, in this case when Dmitry tried other index types.
