[PATCH] scsi: snic: Remove unused linkstatus

[Thomas Fourier]

The (struct vnic_dev).linkstatus buffer is freed in
svnic_dev_unregister() and referenced in svnic_dev_link_status() but
never alloc'd. This means (struct vnic_dev).linkstatus is always null
and the dealloc the reference in svnic_dev_link_status() is dead code.
