[PATCH v14 5/5] xen/blkback: Consistently insert one empty line between functions

[<sjpark@amazon.com>]

From: SeongJae Park <sjpark@amazon.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.
