mount,cmount: run Release asynchronously

Before this change the mount and cmount would run Release synchronously. This would mean that it would wait for files to be closed (eg uploaded) before returning to the kernel. However Release is already running asynchronously from userspace so this commit changes it to do the functionality of Release asynchronously too. This should fix libfuse blocking when Release is active and it is asked to do something else with a file.
