[PATCH v2] efi/capsule-loader: Don't output reset log when reset flags are not set

[Shunyong Yang]

It means firmware attempts to immediately process or launch the capsule
when reset flags in capsule header are not set. 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.
