drm/xe: Add fault injection for xe_sync_entry_parse

pdandamu-star · hghimira · commit 70c7273778bf · 2025-02-21T13:02:54.000+05:30
Add fault injection for xe_sync_entry_parse to allow it to fail while executing xe_vm_bind_ioctl(). This needs to be added as it cannot be reached by injecting error through IOCTL arguments.
