scsi: scsi_transport_iscsi: redirect conn error to console

This commit changes "detected conn error" printk
log level from KERN_INFO to KERN_WARNING.  This change
is made with the assumption that KERN_WARNING messages
are configured to be redirected to console.  It is
particularly useful to have detected connection errors
redirected to console when using iscsi boot device as it
may give clues as to why the system appears to be hung.
