vhost-scsi: Drop vhost_scsi_mutex use in port callouts
We are using the vhost_scsi_mutex to make sure vhost_scsi_port_link and
vhost_scsi_port_unlink see if vhost_scsi_clear_endpoint has cleared
tpg->vhost_scsi and it can't be freed while they are using.
However, we currently set the tpg->vhost_scsi pointer while holding
tv_tpg_mutex. So, we can just hold that while calling
vhost_scsi_hotplug/hotunplug. We then don't need to hold the
vhost_scsi_mutex while vhost_scsi_clear_endpoint is holding it and doing
a flush which could cause the LUN map/unmap to have to wait on another
device's flush.
