efi/capsule-loader: Don't output reset log when reset flags are not set When reset flags in capsule header are not set, it means firmware attempts to immediately process or launch the capsule. Moreover, reset is not needed in this case. The current code will output log to indicate reset. This patch adds a branch to avoid reset log output when the flags are not set.
