x86: CPA fix pagetable split

Browse source

Move the readout of the large entry into the spinlock section to
prevent an unlikely but possible race.

Mark the pmd/pud entry present after the split. We preserved the
non present bit in the new split mapping.

Remove the stale gfp_flags double initialization.
