Acquire spinlock when updating 2PC slot data during logical decoding creation
The creation of a logical decoding context in CreateDecodingContext()
updates some data of its slot for two-phase transactions if enabled by
the caller, but the code forgot to acquire a spinlock when updating
these fields like any other code paths. This could lead to the read of
inconsistent data.
Oversight in a8fd13c.
