change log.Fatal to log.Error to make subsequent os.Exit executable

[Abirdcfly]

We use log "github.com/sirupsen/logrus" for log package:

easeprobe/cmd/easeprobe/main.go

Line 37 in 88fc4e4

log "github.com/sirupsen/logrus"

And we use version 1.9 (show in go.mod)

easeprobe/go.mod

Line 17 in 88fc4e4

github.com/sirupsen/logrus v1.9.0

we use os.Exit(-1) after line 88 log.Fatalln and line 96 log.Fatalf
From Fatalln doc:

Fatalln logs a message at level Fatal on the standard logger then the process will exit with status set to 1.

So subsequent os.Exit(-1) will not executable.

Same with log.Fatalf.

So, here are 2 solutions:
option 1: just delete os.Exit(-1);
option 2: change log.Fatal to log.Error

I think option 2 is more appropriate.
