drm/i915/guc: Drop guc->interrupts.enabled
Drop the variable guc->interrupts.enabled as this variable is just
leading to bugs creeping into the code.
e.g. A full GPU reset disables the GuC interrupts but forgot to clear
guc->interrupts.enabled, guc->interrupts.enabled being true suppresses
interrupts from getting re-enabled and now we are broken.
It is harmless to enable interrupt while already enabled so let's just
delete this variable to avoid bugs like this going forward.
