[i-g-t v7 4/4] tests/intel/xe_vm: Allow scratch page under fault mode on LNL and BMG

[Oak Zeng <oak.zeng@intel.com>]

Due to a fix of out of bound prefetch issue, we now allow scratch
page coexist with fault mode on LNL and BMG. Modify invalid_flag
test to reflect this change.

v1: make the change in invalid_flag (vs caller) (Ashutosh)
