cxl/test: Assign one mock memdev a full-width serial number

Browse source

Mock memdev serial numbers have historically been derived from
pdev->id, leaving them single-digit. As a result they never exercised
either the decimal-vs-hex security-key lookup or unsigned formatting
of large serial numbers.

Give one mock memdev a full-width serial with bit 63 set. This mirrors
real hardware (for example, Montage devices) and provides a test
device that exposes both the hexadecimal-vs-decimal and signed-vs-
unsigned formatting differences.

pdev->id 7 is unused by the auto-region topology so the larger serial
does not affect existing tests.

This enables adding a new test case to cxl-security.sh that verify
auto-unlock using a mock device whose serial exposes both formatting
differences.
