PERFORCE change 18560 for review

[Robert Watson]

This fix appears not to.  The bug I think you're running into has to do
with how UFS2 layers EA services on top of the existing write API, relying
on IO_EXT to address them to the right extent.  Since specfs implements
the VOP_WRITE() implementation for UFS2 device nodes, this breaks.  I've
forwarded some details to phk.
