We need to clear the register in order to get correct value after the
next potential hang.

We already have i915_clear_error_registers() high up in the caller. I'd
like to pull i915_check_and_clear_faults() into
i915_clear_error_registers, and so also clear the error regs on take
over like we do for faults.
