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
