MdeModulepkg VarCheckLib: Return NULL when no property set 

to variable with wildcard name.

VarCheckLib has zeroed property for variable with wildcard name
and is waiting for property set. The code should return NULL
when no property set to variable with wildcard name, but not
return the zeroed property that will impact the functionality of
SetVariableCheck.

The issue does not appear with VarCheckUefiLib linked as the library
just has the expected property set.
