[Xen-devel] [[PATCH v2]] libxl/arm: Fix ARM build.

[Andrii Anisov <andrii.anisov@xxxxxxxxx>]

From: Andrii Anisov <andrii_anisov@xxxxxxxx>

Initialise *size in default branch to prevent certain compilers (i.e.
Linaro GCC 5.2-2015.11-2) from reporting "variable may be used uninitialized"
errors in caller function.
