Subject: [PATCH] sd-event: change error code -EINVAL -> -EIO

EINVAL should be used when a function is called with an invalid
argument. Here, the signal is not a function argument.

Follow-up for 7a64c5f23efbb51fe4f1229c1a8aed6dd858a0a9.

(cherry picked from commit ab9af70edb23f2a66e93e2e16f87cd98873885b7)
