Bluetooth: btmtksdio: fix usage_count leak when autosuspend_delay is negative
btmtksdio_setup() calls pm_runtime_use_autosuspend() when runtime PM
is supported, but btmtksdio_remove() does not call the matching
pm_runtime_dont_use_autosuspend() when removing the device.
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 driver teardown, this reference is not dropped and usage_count
remains unbalanced.
Add the missing pm_runtime_dont_use_autosuspend() call in the remove
path before restoring the runtime PM usage reference.
This issue was found by manual code inspection.
