qeth: postpone open till recovery is finished

The open function of qeth is not executed if the qeth device is in
state DOWN or HARDSETUP. A recovery switches from state SOFTSETUP to
HARDSETUP to DOWN to HARDSETUP and back to SOFTSETUP. If open and
recover are running concurrently, open fails if it hits the states
HARDSETUP or DOWN. This patch inserts waiting for recovery finish
in the qeth open functions to enable successful qeth device opening
in spite of a running recovery.
