Wang Nan 421fd0845e perf probe: Verify parameters in two functions ...

On kernel with only one out of CONFIG_KPROBE_EVENTS and
CONFIG_UPROBE_EVENTS enabled, 'perf probe -d' causes a segfault because
perf_del_probe_events() calls probe_file__get_events() with a negative
fd.

This patch fixes it by adding parameter validation at the entry of
probe_file__get_events() and probe_file__get_rawlist(). Since they are
both non-static public functions (in .h file), parameter verifying is
required.

v1 -> v2: Verify fd at the head of probe_file__get_rawlist() instead of
          checking at call site (suggested by Masami and Arnaldo at [1,2]).
