[PATCH i-g-t 1/2] tests/intel/xe_fault_injection: Inject errors during xe_guc_mmio_send_recv

[Satyanarayana K V P]

Use the kernel fault injection infrastructure to test error handling
of xe at probe time when executing xe_guc_mmio_send_recv() so that
more code paths are tested, such as error handling and unwinding.

Error can be injected using:
./xe_fault_injection --run-subtest inject-fault-probe-function-xe_guc_mmio_send_recv
