Carl Henrik Lunde 14a73f5479 block: disable IRQs until data is written to relay channel 
As we may run relay_reserve from interrupt context we must always disable
IRQs.  This is because a call to relay_reserve may expose previously written
data to use space.

Updated new message code and an old but related comment.
