x86/smpboot: Fix INIT delay assignment for extended Intel Families
Some old crusty CPUs need an extra delay that slows down booting. See
the comment above 'init_udelay' for details. Newer CPUs don't need the
delay.
Right now, for Intel, Family 6 and only Family 6 skips the delay. That
leaves out both the Family 15 (Pentium 4s) and brand new Family 18/19
models.
The omission of Family 15 (Pentium 4s) seems like an oversight and 18/19
do not need the delay.
Skip the delay on all Intel processors Family 6 and beyond.
