vhost-scsi: Drop device mutex use in vhost_scsi_do_plug

We don't need the device mutex in vhost_scsi_do_plug because:
1. we have the vhost_scsi_mutex so the tpg->vhost_scsi pointer will not
change on us and the vhost_scsi can't be freed from under us if it was
set.
2. vhost_scsi_clear_endpoint will stop the virtqueues and flush them while
holding the vhost_scsi_mutex so we know once vhost_scsi_clear_endpoint
has completed that vhost_scsi_do_plug can't send new events and any
queued ones have completed.

So this patch drops the device mutex use in vhost_scsi_do_plug.
