HID: rate-limit hid_warn to prevent log flooding
Syzkaller can create many uhid devices that trigger
repeated warnings like:
"hid-generic xxxx: unknown main item tag 0x0"
These messages can flood the system log, especially if a crash occurs
(e.g., with a slow UART console, leading to soft lockups). To mitigate
this, convert `hid_warn()` to use `dev_warn_ratelimited()`.
This helps reduce log noise and improves system stability under fuzzing
or faulty device scenarios.
