uprobes: Fix return value in error handling path

When wrong argument is passed into uprobe_events it does not return
an error:

[root@jovi tracing]# echo 'p:myprobe /bin/bash' > uprobe_events
[root@jovi tracing]#

The proper response is:

[root@jovi tracing]# echo 'p:myprobe /bin/bash' > uprobe_events
-bash: echo: write error: Invalid argument
