io_uring: annotate remote tasks for kcoverage
Fuzzers use coverage information to guide generation of test cases
towards new or interesting code paths. Syzkaller, specifically, makes
use kcoverage (CONFIG_KCOV). Coverage information is not collected for
kernel tasks unless annotated by kcov_remote_start and kcov_remote_stop.
This patch annotates io-uring's work queue and sqpoll tasks.
