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
