Analyze and fix the following issue in the Linux kernel code: drm/i915/huc: Cancel HuC delayed load timer on reset.
Problem Details: In the rare case where we do a full GT reset after starting the HuC load and before it completes (which basically boils down to i915 hanging during init), we need to cancel the delayed load fence, as it will be re-initialized in the post-reset recovery.

We would only lock in non-atomic context in this driver, so use a mutex instead, which is friendlier if we need to schedule when iterating.
