x86/mm: Fix no-change case in try_preserve_large_page()
try_preserve_large_page() checks if new_prot is the same as
old_prot. If so, it simply sets do_split to 0, and returns
with no-operation. However, old_prot is set as a 4KB pgprot
value while new_prot is a large page pgprot value.
Now that old_prot is initially set from p?d_pgprot() as a
large page pgprot value, fix it by not overwriting old_prot
with a 4KB pgprot value.
