Fix TwoPhaseGetDummyBackendId().
This was broken in commit ed0b409d22346b1b027a4c2099ca66984d94b6dd,
which revised the GlobalTransactionData struct to not include the
associated PGPROC as its first member, but overlooked one place where
a cast was used in reliance on that equivalence.
The most effective way of fixing this seems to be to create a new function
that looks up the GlobalTransactionData struct given the XID, and make
both TwoPhaseGetDummyBackendId and TwoPhaseGetDummyProc rely on that.
Per report from Robert Ross.
