[PATCH] efi_loader: Don't warn if the TCG2 FinalEvents table is not installed

[Ilias Apalodimas]

When the TCG2 protocol installation fails, we are trying to remove
all the objects we created in tcg2_uninit().

However, there are cases when this function runs before the config
table was installed. So instead of printing an error unconditionally
check against EFI_NOT_FOUND and don't print anything if the table wasn't
installed to begin with.
