[SCSI] rework scsi_target allocation
The current target allocation code registeres each possible target with sysfs; it will be deleted again if no useable LUN on this target was found. This results in a string of 'target add/target remove' uevents. Based on a patch by Hannes Reinecke <hare@suse.de> this patch reworks the target allocation code so that only uevents for existing targets are sent. The sysfs registration is split off from the existing scsi_target_alloc() into a in a new scsi_add_target() function, which should be called whenever an existing target is found. Only then a uevent is sent, so we'll be generating events for existing targets only. Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
