[PATCH] libxl/disk: avoid aliasing of abs()

[Jan Beulich <jbeulich@xxxxxxxx>]

Tool chains with -Wshadow enabled by default won't like the function
parameter name "abs", for aliasing stdlib.h's abs(). Rename the
parameter to what other similar functions use.

Fixes: a18b50614d97 ("libxl: Enable stubdom cdrom changing")
