tests: handle multiple devs with wait_pvmove_lv_ready

aux wait_pvmove_lv_ready() now handles multiple pvmove LVs
at one go - which allows a bit fast checking - although
at some point we may need to switch to use delayed devs
since mirror throttling seems to be no longer working well,
as CPU are getting so fast, that most of data are already
pvmoved before throttling has any chance to do something...
