Subject: [PATCH] perf dlfilter: Drop unused variable

Compiling tools/perf/dlfilters/dlfilter-test-api-v0.c result in:

	checking for stdlib.h... dlfilters/dlfilter-test-api-v0.c: In function ‘filter_event’:
	dlfilters/dlfilter-test-api-v0.c:311:29: warning: unused variable ‘d’ [-Wunused-variable]
	  311 |         struct filter_data *d = data;
	      |

So remove the  variable now.
