Fix ide emulation bugkvm-44
With very recent kernels libata throws lots of errors while booting and it
makes booting really really slow, while searching the solution i found
following bug reports [1],[2] and following commit [3].
Following diff against kvm-userspace HEAD solves this issue for kvm. This
chunk of code is directly copied from qemu CVS so according to CVS logs
credit belongs to Brandon Philips.
