arm64: mm: Change page table pointer name in p[md]_set_huge()

Browse Source 
This is preparation for the following backported fixes.  It was done
upstream as part of commit 20a004e7b0 "arm64: mm: Use
READ_ONCE/WRITE_ONCE when accessing page tables", the rest of which
does not seem suitable for stable.
