mm/x86: replace p4d_large() with p4d_leaf()
p4d_large() is always defined as p4d_leaf(). Merge their usages. Chose
p4d_leaf() because p4d_leaf() is a global API, while p4d_large() is not.
Only x86 has p4d_leaf() defined as of now. So it also means after this
patch we removed all p4d_large() usages.
