xen/arm: mm: fix nr_second calculation in setup_frametable_mappings
On ARM64, "frametable_size >> SECOND_SHIFT" computes the number
of second level entries, not the number of second level pages.
"ROUNDUP(frametable_size, FIRST_SIZE) >> FIRST_SHIFT" which computes
the number of the first level entries (the number of second level pages),
is the correct one that should be used.
