[PATCH i-g-t v4 1/2] tests/intel/xe_fault_injection: Inject errors during xe_guc_mmio_send_recv

[Satyanarayana K V P <satyanarayana.k.v.p@intel.com>]

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:
igt@xe_fault_injection@inject-fault-probe-function-xe_guc_mmio_send_recv

v2: Sorted the entry xe_guc_mmio_send_recv in inject-fault-probe-function-* list
