  x86/resctrl: Fix a maybe-uninitialized build warning treated as error (2021-08-22 09:11:29 +0200)

----------------------------------------------------------------
- Fix build error on RHEL where -Werror=maybe-uninitialized is set.

- Restore the firmware's IDT when calling EFI boot services and before
ExitBootServices() has been called. This fixes a boot failure on what
appears to be a tablet with 32-bit UEFI running a 64-bit kernel.
