iotests: Make 030 less flaky
This patch fixes two race conditions in 030:
1. The first is in TestENOSPC.test_enospc(). After resuming the job,
querying it to confirm it is no longer paused may fail because in the
meantime it might have completed already. The same was fixed in
TestEIO.test_ignore() already (in commit
2c3b44da07d341557a8203cc509ea07fe3605e11).
2. The second is in TestSetSpeed.test_set_speed_invalid(): Here, a
stream job is started on a drive without any break points, with a
block-job-set-speed invoked subsequently. However, without any break
points, the job might have completed in the meantime (on tmpfs at
least); or it might complete before cancel_and_wait() which expects
the job to still exist. This can be fixed like everywhere else by
pausing the drive (installing break points) before starting the job
and letting cancel_and_wait() resume it.
