perf tools: Fix perf tool build error in util/pfm.c

I have downloaded linux-next and build the perf tool using

  # make LIBPFM4=1

to have libpfm4 support built into perf. The build fails:

 # make LIBPFM4=1
....
INSTALL libbpf_headers
  CC      util/pfm.o
util/pfm.c: In function ‘print_libpfm_event’:
util/pfm.c:189:9: error: too many arguments to function ‘print_cb->print_event’
  189 |         print_cb->print_event(print_state,
      |         ^~~~~~~~
util/pfm.c:220:25: error: too many arguments to function ‘print_cb->print_event’
  220 |                         print_cb->print_event(print_state,

The build error is caused by commit d9dc887 ("perf pmu-events:
Remove now unused event and metric variables") which changes the
function prototype of

  struct print_callbacks {
      ...
      void (*print_event)(...);  --> last two parameters removed.
  };

but does not adjust the usage of this function prototype in util/pfm.c.
In file util/pfm.c function print_event() is still invoked with 13
parameters instead of 11. The compile fails.

When I adjust the file util/pfm.c as in this patch, the build works file.
Please check this patch for correctness, I have just fixed the compile
issue.
