MdeModulePkg/Core/Dxe: free page 0 after disabling NULL pointer detection
To solve access issue reported by BZ1885, page 0 will be allocated to
avoid misuses if NULL pointer detection is enabled. It should be better
to be freed after EndOfDxe if BIT7 of PcdNullPointerDetectionPropertyMask
is set, because NULL pointer detection is no longer available after
EndOfDxe and there will be no access conflict.
