Two variables that are only used in an #ifdef cause compiler warnings:

lib/test_xarray.c: In function 'check_xa_tag_1':
lib/test_xarray.c:162:15: error: unused variable 'order' [-Werror=unused-variable]
  unsigned int order;

lib/test_xarray.c: In function 'check_xa_shrink':
lib/test_xarray.c:288:15: error: unused variable 'order' [-Werror=unused-variable]
  unsigned int order;

Add another #ifdef around the declaration to avoid the warning.

Fixes: 4f79afaf4662 ("xarray: Move multiorder_shrink to kernel tests")
Fixes: 137689411a26 ("xarray: Move multiorder account test in-kernel")
