rate-submit: call ioengine post_init when starting workers

ioengines with post_init steps were not fully fully initialized by
offload worker threads because the post_init function was never called.

Without this patch all libaio operations submitted in offload mode fail
because the ioengine was not fully initialized.

Fixes: 2041bd343da1 ("engines/libaio: add preliminary support for pre-mapped IO buffers")
