plugin/amdgpu: Don't print error for "No such process" during resume

Browse source 
During the late stages of restore, each process being resumed gets
an ioctl call to KFD_CRIU_OP_RESUME. If the process has no kfd
process info, this call with fail with -ESRCH. This is normal
behaviour, so we shouldn't print an error message for it.
