Bluetooth: hci_intel: fix usage_count leak when autosuspend_delay is negative
intel_set_power() calls pm_runtime_use_autosuspend() when powering on
the device, but the power-off path does not call the matching
pm_runtime_dont_use_autosuspend() before disabling runtime PM.
If the autosuspend delay is set to a negative value while autosuspend
is enabled, the runtime PM core increments usage_count to prevent
runtime suspend. Without calling pm_runtime_dont_use_autosuspend()
during teardown, this reference is not dropped and usage_count remains
unbalanced.
Add the missing pm_runtime_dont_use_autosuspend() call before disabling
runtime PM.
This issue was found by manual code inspection.
