Initially, printf was used to indicate and error/warning resulting from
telemetry initialisation. This is now fixed to use EAL logs for
warnings, and the unnecessary printf for an error is removed.

Fixes: eeb486f3ba65 ("eal: add telemetry as dependency")
Fixes: dd6275a424ac ("telemetry: fix error log output")
Cc: david.marchand@redhat.com
