irqbalance: Fix log spam and correct meson version
Irqbalance 1.9.3 changed the handling of certain errors.
Specifically EINVAL, trying to set an invalid CPU core,
was changed to be a temporary error, causing log spam from
repeated balancing runs in some devices. See log and strace below.
Mark EINVAL as permanent.
Also correct the version in our own meson.build patch.
Log and strace:
