Subject: [PATCH] drm/panic: clean Clippy warning

Clippy warns:

    error: manual implementation of an assign operation
       --> drivers/gpu/drm/drm_panic_qr.rs:418:25
        |
    418 |                         self.carry = self.carry % pow;
        |                         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: replace it with: `self.carry %= pow`
        |
        = help: for further information visit https://rust-lang.github.io/rust-clippy/master/index.html#assign_op_pattern

Thus clean it up.
