Bluetooth: btmtksdio: Fix PM runtime reference leak in shutdown
In btmtksdio_shutdown(), pm_runtime_get_sync() is called at the
beginning of the function. However, if sending the WMT function
control command fails later, the driver returns early.
It bypasses the corresponding pm_runtime_put_noidle() and
pm_runtime_disable() calls, leaking the PM usage counter and leaving PM
runtime enabled indefinitely.
Fall through to execute the PM runtime cleanup block even if WMT errors.
Fixes: 7f3c563c575e ("Bluetooth: btmtksdio: Add runtime PM support to SDIO based Bluetooth")
