3a1c694d74deb478d9822e585e90c5903852eb84 rust: qom: fix TODO about zeroability of classes
The proposed suggestion is not correct. First it is not necessary for
*all* classes to be Zeroable, only for Rust-defined ones; classes
defined in C never implement ObjectImpl.
Second, the parent class field need not be Zeroable. For example,
ChardevClass's chr_write and chr_be_event fields cannot be NULL,
therefore ChardevClass cannot be Zeroable. However, char_class_init()
initializes them, therefore ChardevClass could be subclassed by Rust code.
