drm/amdkfd: Check bounds on CRIU restore event id

drm/amdkfd: Check bounds on CRIU restore event id

The valid amdkfd event ids go from 0 to KFD_SIGNAL_EVENT_LIMIT - 1.

During CRIU restore, ensure that the provided event ids are
in that range.

v2: No need for lower bound check since idr_alloc rejects negative
inputs

v3: Also change error message to reflect new error condition
