exfat: reduce unnecessary writes during mmap write
During mmap write, exfat_page_mkwrite() currently extends
valid_size to the end of the VMA range. For a large mapping,
this can push valid_size far beyond the page that actually
triggered the fault, resulting in unnecessary writes.
valid_size only needs to extend to the end of the page
being written.
