Subject: [PATCH v11 6/6] xen/blkback: Consistently insert one empty line between functions

From: SeongJae Park <sjpark@...zon.de>

The number of empty lines between functions in the xenbus.c is
inconsistent.  This trivial style cleanup commit fixes the file to
consistently place only one empty line.
