rust: init: Fix generics in *_init! macros

The match pattern for a optional trailing comma in the list of generics
is erroneously repeated in the code block resulting in following error:

| error: attempted to repeat an expression containing no syntax variables matched as repeating at this depth
|    --> rust/kernel/init.rs:301:73
|     |
| 301 |         ::pin_init::try_pin_init!($(&$this in)? $t $(::<$($generics),* $(,)?>)? {
|     |                                                                         ^^^

Remove "$(,)?" from all code blocks in the try_init! and try_pin_init!
definitions.
