iommu/arm-smmu: Delete an unnecessary check before the function call "free_io_pgtable_ops"

Browse Source 
The free_io_pgtable_ops() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
