All set_pte_safe() usage have been dropped after the commit eccd906484d1
("x86/mm: Do not use set_{pud, pmd}_safe() when splitting a large page")
This just drops now unused helper set_pte_safe().
Besides this macro was buggy due to doing direct dereferencing of the pte,
and if it were to be kept, it should have been updated to use a single call
to ptep_get().
