The variable is never referenced in the code, just remove them.

There is usually a space after the colon in the subject:

	"samples/bpf: Remove unused variable"

Also a subject prefix "bpf-next" is needed. You can add it when
formatting the patch:

	git format-patch -1 --subject-prefix='PATCH bpf-next'
