efi: efibc: Guard against allocation failure

There is a single kmalloc in this driver, and it's not currently
guarded against allocation failure. Do it here by just bailing-out
the reboot handler, in case this tentative allocation fails.

Fixes: 416581e48679 ("efi: efibc: avoid efivar API for setting variables")
