perf probe: Add warning message if there is unexpected event name
This improve the error message so that user can know event-name error
before writing new events to kprobe-events interface.
E.g.
======
#./perf probe -x /lib64/libc-2.25.so malloc_get_state*
Internal error: "malloc_get_state@GLIBC_2" is an invalid event name.
Error: Failed to add events.
