[PATCH v3 1/2] efi_loader: fix set_capsule_result()

The log category must be LOG_CATEGORY LOGC_EFI.
efi_set_variable() should be called with EFI_CALL(). Use
efi_set_variable_int() instead.
A log text "Updating ..." if SetVariable() fails does not make sense for a
variable that is not required to be preexisting.
