  efi_loader: fix the return values on efi_tcg (2024-06-24 08:38:06 +0300)

The CI is here https://source.denx.de/u-boot/custodians/u-boot-tpm/-/pipelines/21309
and showed no problems.

I also tested measured booot looking at the EventLog pre/post patch. No changes
apart from PCR0 which is expected to change

----------------------------------------------------------------
When the EFI TCG measurement code moved from EFI to the TPM subsystem for
general use some prototypes changed from returning efi_status_t to int,
which is more appropriate for the non-EFI APIs. However, some of the
EFI callsites never changed and we ended up assigning the int value to
efi_status_t.

This is unlikely to cause any problems, apart from returning invalid
values on failures and violating the EFI spec.
