Two fixes and one cleanup for the FIFO-based event channel ABI.
The first fixes an early hang when resuming guests -- this often
occured with PVHVM guests but PV guests for some reason got away with
it...
The second fixes a rare crash if 1023 event channels (or more) were
used -- this would typically only affect dom0.

(although evtchn_fifo_init_control_block() vs init_control_block()
naming in patch 1 is slightly confusing I think).

I'll change the first to evtchn_fifo_alloc_control_block(). Is that ok?

Applied to devel/for-linus-2.17 since they're not a 3.16 regression and
3.16 is nearly here.
