UPSTREAM: kcov: simplify interrupt check
in_interrupt() semantics are confusing and wrong for most users as it
also returns true when bh is disabled. Thus we open coded a proper
check for interrupts in __sanitizer_cov_trace_pc() with a lengthy
explanatory comment.
Use the new in_task() predicate instead.
