iscsi-test-cu: Improve persistent reservation clearing

Browse Source 
Clear persistent reservations before sending the first SCSI command to the
target to avoid that that command fails due to persistent reservations left
behind by a previous run of the test tool.

Avoid that a subsequent test fails if a test did not remove the persistent
reservations it obtained.

Make sure that clear_pr() returns -1 if clearing persistent reservations
fails.
