drm/i915/psr: Fix warning in intel_psr_activate()
commit 5422b37c907e ("drm/i915/psr: Kill delays when activating psr
back.") removed the call to cancel a scheduled psr_work from
psr_disable() and instead added an early return in the work function. But,
if the scheduled work item is executed after psr_enable(), we end up
printing warnings as PSR is already enabled and active. So, put the
cancel_work call back in psr_disable().
