[PATCH] efi: loader: reduce warning about non-persistent EFI variables to notice

[Ahmad Fatoum]

When booting an EFI-stubbed kernel outside of an ESP, we always get:

  WARNING: efi-loader: var-file: Cannot persist EFI variables without
  system partition

A warning is arguably a bit harsh, because one still benefits from
keeping the MMU enabled and the other EFI runtime services, so bump to a
notice log level instead.
