[PATCH 03/10] 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 patch.
