pc: fix KVM features in pc-1.3 and earlier machine types

Due to a typo, instead of disabling KVM_FEATURE_PV_EOI (bit
6) these machine types are disabling bits 1 and 2, which are
KVM_FEATURE_NOP_IO_DELAY and KVM_FEATURE_MMU_OP.  Not a big deal
because they aren't very important and KVM_FEATURE_MMU_OP is
disabled anyway.  The worst part is actually that KVM_FEATURE_PV_EOI
is remaining enabled.
