[LU-12672] recovery-small test 66 does not work correctly

Examining logs I discovered there's something wrong with hole recovery-small test 66 determines mdc cli name and so attempts to set/reset it fail:

Comparing to other users, determining it as

mdccli=$($LCTL dl | awk '/-MDT0000-mdc-/ {print $4;}')

seems to be wrong, every other bit of code seems to be getting it as

mdccli=$($LCTL dl | grep "${mdtname}-mdc" | awk '{print $4;}')

Sure, it's an extra grep which is not ideal but it appears to be actually doing he filterign as opposed to the awk? (see the MDT0001 somehow making the appearance in the output.
