kvm: remove one useless check extension 



We already check KVM_CAP_IRQFD in generic once enable CONFIG_HAVE_KVM_IRQFD,

kvm_vm_ioctl_check_extension_generic()
    |
    + switch (arg) {
    +   ...
    +   #ifdef CONFIG_HAVE_KVM_IRQFD
    +       case KVM_CAP_IRQFD:
    +   #endif
    +   ...
    +   return 1;
    +   ...
    + }
    |
    + kvm_vm_ioctl_check_extension()

So its not necessary to check this in arch again, and also fix one typo,
s/emlation/emulation.
