Christophe JAILLET 6ac2adcc2b iommu/vt-d: Fix an unbalanced rcu_read_lock/rcu_read_unlock() 
commit 4e5973dd2725bb30c3db622f7d73f7a5864ce718 upstream.

If we return -EOPNOTSUPP, the rcu lock remains lock. This is spurious.
Go through the end of the function instead. This way, the missing
'rcu_read_unlock()' is called.

Fixes: 7afd7f6aa21a ("iommu/vt-d: Check FL and SL capability sanity in scalable mode")
