Daniel Gustafsson 25b922ec58 Fix invalid checksum state transition in checkpoints 
Commit 78e950cb8 added checksum state handling to all XLOG_CHECKPOINT
records which caused unnecessary state transitions and emission of
procsignal barriers.  Remove as only the _REDO record need to handle
checksum state.  Barrier emission is also consistently made after
controlfile updates to avoid race conditions.

Additionally, interrupts are held between calling ProcSignalInit and
InitLocalDataChecksumState to remove a window where otherwise invalid
state transitions can happen.

Also remove a pointless assertion on Controlfile which will never hit.
