description:
lib: ioloop-epoll didn't correctly check if there were any IO events.
Alternatively we could have checked for array_count(&ctx->events) >
ctx->deleted_count, but this code is a bit more understandable.

This change doesn't actually fix any proper bugs, it just causes the process
to crash instead of going to infinite wait loop.
