[PATCH v2 3/5] hotplug/NetBSD: check type of file to attach from params

[Roger Pau Monne <roger.pau@citrix.com>]

xend used to set the xenbus backend entry "type" to either "phy" or
"file", but now libxl sets it to "phy" for both file and block device.
We have to manually check for the type of the "param" filed in order
to detect if we are trying to attach a file or a block device.

Changes since v1:

 * Check that file is either a block special file or a regular file
   and report error otherwise.
