xen: use less generic names in blkfront driver.
All Xen frontend drivers have a couple of identically named functions which makes figuring out which device went wrong from a stacktrace harder than it needs to be. Rename them to something specificto the device type. Signed-off-by: Ian Campbell <ian.campbell@citrix.com> Cc: Jeremy Fitzhardinge <jeremy.fitzhardinge@citrix.com>
