-----------
MdeModulePkg/BootMaintenanceManagerUiLib: Check array index before access
Many arrays are defined with a length of MAX_MENU_NUMBER in
FormGuid.h. Two of those are BootOptionOrder and DriverOptionOrder.
In UpdatePage.c, a pointer is set to either of those arrays. The
array buffer is accessed using an index whose range is checked after
the pointer to the array is dereferenced. This change moves the check
before the dereference.
In another place in the file, the ConsoleCheck pointer is also set to
an array buffer with MAX_MENU_NUMBER elements. Only an ASSERT()
currently checks the range of the array index. This change
conditionalizes the pointer dereference itself on the range of Index.
