Lu Baolu c56cba5daf iommu/vt-d: Fix NULL pointer reference in intel_svm_bind_mm() 
Intel IOMMU could be turned off with intel_iommu=off. If Intel
IOMMU is off,  the intel_iommu struct will not be initialized.
When device drivers call intel_svm_bind_mm(), the NULL pointer
reference will happen there.

Add dmar_disabled check to avoid NULL pointer reference.
