Oleksandr Tyshchenko a175a67d30 iommu/ipmmu-vmsa: Rereserving a free context before setting up a pagetable 
Reserving a free context is both quicker and more likely to fail
(due to limited hardware resources) than setting up a pagetable.
What is more the pagetable init/cleanup code could require
the context to be set up.
