scsi: core: Remove the put_device() call from scsi_device_get()
scsi_device_get() may be called from atomic context, e.g. by
shost_for_each_device(). A later commit will allow put_device() to sleep
for SCSI devices. Hence remove the put_device() call from
scsi_device_get().
According to Rusty Russell's "Module Refcount and Stuff mini-FAQ", calling
module_put() from atomic context is allowed since considerable time. See
also https://lkml.org/lkml/2002/11/18/330.
