Removal of the message "No I/O performed" when fio does not execute any
I/O broke zbd tests 2 and 3 as this message is looked after to test for
success. Fix this by looking for a "Run status" line starting with
"WRITE:" for test 2 and "READ:" for test 3. The run status lines are not
printed when no I/O is performed. Testing for the absence of these
strings thus allows to easily test if I/Os where executed or not.
Fixes: ff3aa922570c ("Kill "No I/O performed by ..." message")
