Fix: Lock metadata cache on session destroy

commit 92143b2c5656 ("Fix: metadata stream leak, missing list removal and locking")
missed taking a lock protecting the metadata stream list iteration on
session destroy. This opens a race window between iteration and item
removal/free which triggers kernel OOPS.
