kernel: WARNING: CPU: 1 PID: 1404 at drivers/scsi/qla2xxx/qla_target.c:6654 qlt_enable_vha+0x1e0/0x280 [qla2xxx]

The issue happens because no real ISP reset is executed.  The
qla2x00_abort_isp(scsi_qla_host_t *vha) function expects that
vha->flags.online will be not zero for ISP reset procedure.  This patch
sets vha->flags.online to 1 before calling ->abort_isp() for starting the
ISP reset.
