[CORE,HW] replace using of Paged pool by NonPaged one. [mlnx: 4836]

We see from time to time BSODs at shutdown times while a hard traffic load.
It can be attributed to the fact that some of the structured used in PnP and Power Management are allocated in Paged Pool.
As far as these structures are of little size it is safer to use for them always NonPagedPool.
It makes the driver more robust.
