powerpc/kuap: Fold kuep_is_disabled() into its only user
kuep_is_disabled() was introduced by commit 91bb30822a2e ("powerpc/32s: Refactor update of user segment registers") but then all users but one were removed by commit 526d4a4c77ae ("powerpc/32s: Do kuep_lock() and kuep_unlock() in assembly"). Fold kuep_is_disabled() into init_new_context() which is its only user.
