The current error handling in init_srcu_struct_fields() is a bit inconsistent. If init_srcu_struct_nodes() fails, the function either returns -ENOMEM or 0 depending on whether ssp->sda_is_static is true or false. This can make init_srcu_struct_fields() return 0 even if memory allocation failed! Simplify the error handling by always returning -ENOMEM if either init_srcu_struct_nodes() or the per-CPU allocation fails. This makes the control flow easier to follow and avoids the inconsistent return values. Add goto labels to avoid duplicating the error cleanup code.
