[PATCH] pmcraid: add missing scsi_device_put() in pmcraid_eh_target_reset_handler()

[Hannes Reinecke <hare@suse.de>]

(Re-sending as a separate patch:)
When breaking out of a shost_for_each_device() loop one need to do
an explicit scsi_device_put(). And while at it convert to use
shost_priv() instead of a direct reference to ->hostdata.

Fixes: c2a14ab3b9b3 ("scsi: pmcraid: Select device in pmcraid_eh_target_reset_handler()")
