[PATCH 5.9 253/757] Bluetooth: Re-order clearing suspend tasks

[Greg Kroah-Hartman]

From: Abhishek Pandit-Subedi <abhishekpandit@xxxxxxxxxxxx>

[ Upstream commit 3eec158d5eca7dd455118d9e00568aad2371219f ]

Unregister_pm_notifier is a blocking call so suspend tasks should be
cleared beforehand. Otherwise, the notifier will wait for completion
before returning (and we encounter a 2s timeout on resume).

Fixes: 0e9952804ec9c8 (Bluetooth: Clear suspend tasks on unregister)
