x86: CPA: fix gbpages support in try_preserve_large_page

Browse source 
[ 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.
