Neither uc_pdata->name nor check_name are supposed to be NULL in _rproc_name_is_unique(). if uc_pdata->name is NULL, we are not intialized yet, however if check_data is NULL, we do not have proper data. Further, if either were NULL, strlen will crap out while attempting to derefence NULL.

Instead, just check if either of these are NULL and bail out.

This should also fix the following coverity scan warnings: *** CID 132281: Null pointer dereferences (FORWARD_NULL) /drivers/remoteproc/rproc-uclass.c: 73 in _rproc_name_is_unique()
