perf cs-etm: Add missing variable in cs_etm__process_queues()

Commit 5afd032961e8 "perf cs-etm: Don't flush when packet_queue fills
up" uses i as a loop counter in cs_etm__process_queues().  It was
backported to the 5.4 and 5.10 stable branches, but the i variable
doesn't exist there as it was only added in 5.15.

Declare i with the expected type.
