[PATCH] dmicheck: fix handling of type 16 capacities > 2 TiB

[Robert Elliott]

In the SMBIOS type 16 (Physical Memory Array) record, a Maximum Capacity
field of 0x80000000 means that the capacity is reported in the
Extended Maximum Capacity field.  However, that value triggers this
error:

FAILED [HIGH] DMIValueOutOfRange: Test 2, Out of range value 0x80000000 (range
allowed 0x0000..0x7fffffff) while accessing entry 'Physical Memory Array (Type
16)' @ 0x8a02f1fd, field 'Maximum Capacity', offset 0x07

check: Out of range value 0x80000000 (range allowed 0x0000..0x7fffffff) while accessing entry 'Physical Memory Array (Type 16)' @ 0x8a02f1fd, field 'Maximum Capacity',
 offset 0x07

Modify the Maximum Capacity range check to exclude that value.
