Masami Hiramatsu f192874afd perf probe: Add warning message if there is unexpected event name

[ Upstream commit 9f5c6d8777a2d962b0eeacb2a16f37da6bea545b ]

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.
   ======
