mirror: fix request throttling in drive-mirror
There are 2 deficiencies here:
- mirror_iteration could start several requests inside. Thus we could
simply have more in_flight requests than MAX_IN_FLIGHT.
- keeping this in mind throttling in mirror_run which is checking
s->in_flight == MAX_IN_FLIGHT is wrong.
The patch adds the check and throttling into mirror_iteration and fixes
the check in mirror_run() to be sure.
