svn commit: r261600 - head/sys/dev/bvm

[John Baldwin]

Author: jhb
Date: Fri Feb  7 15:10:24 2014
New Revision: 261600
URL: http://svnweb.freebsd.org/changeset/base/261600

Log:
  - Use a callout instead of the deprecated timeout_handle.
  - Set the console name always so that the bvm console device can be used
    via conscontrol even if it isn't chosen as the default console.
