x86: CPA: fix gbpages support in try_preserve_large_page
[ mingo@elte.hu: while gbpages cannot be enabled on mainline currently,
keep the code uptodate and this fix is easy enough. ]
Use correct page sizes and masks for GB pages in try_preserve_large_page()
This prevents a boot hang on a GB capable system with CONFIG_DIRECT_GBPAGES
enabled.
