Jian J Wang 9b17c6511d MdeModulePkg/Core: fix feature conflict between NX and NULL detection
If enabled, NX memory protection feature will mark all free memory as
NX (non-executable), including page 0. This will overwrite the attributes
of page 0 if NULL pointer detection feature is also enabled and then
compromise the functionality of it. The solution is skipping the NX
attributes setting to page 0 if NULL pointer detection feature is enabled.
