drm/xe: Assume large page size if VMA not yet bound 



The calculation to determine max page size of a VMA during a REMAP
operations assumes the VMA has been bound. This assumption is not true
if the VMA is from an eariler operation in an array of binds. If a VMA
has not been bound use the maximum page size which will ensure the
previous / next REMAP operations are not incorrectly skipped.
