winverbs: ensure that event and mutex memory are resident

winverbs: ensure that event and mutex memory are resident

The winverbs PD structure contains both an event and a guarded mutex.  Both must
be allocated as part of resident memory, or vague system corruptions may occur
if their memory is paged out.

The fix is to allocate the PD structure from NonPagedPool.
