[PATCH] tests/intel/xe_configfs: Add malformed multi-line BB to verify ctx rejection and rollback

[Smitha Balasubramanyam <smitha.balasubramanyam@intel.com>]

Add a test vector with a partially invalid second command in the
ctx_restore_*_bb invalid-case suite to ensure a malformed multi-line
BB is rejected and the stored BB remains empty (rollback).
