entry: Move irqentry_enter() prototype later
Subsequent patches will rework the irqentry_*() functions. The end
result (and the intermediate diffs) will be much clearer if the
prototype for the irqentry_enter() function is moved later, immediately
before the prototype of the irqentry_exit() function.
Move the prototype later.
This is purely a move; there should be no functional change as a result
of this change.
