drm/shmem_helper: Check VMA boundaries for PMD mappings
In the ->huge_fault handler do not install a PMD huge page
mapping if the huge page exceeds the boundaries of the VMA.
All other ->huge_fault handlers have similar checks and the
resulting mapping will trigger a VM_BUG_ON_VMA() if it ever
reaches copy_pmd_range().
