sparc64: Fix DAX handling via userspace access from kernel.
[ Upstream commit fcd26f7ae2ea5889134e8b3d60a42ce8b993c95f ]
If we do a userspace access from kernel mode, and get a
data access exception, we need to check the exception
table just like a normal fault does.
The spitfire DAX handler was doing this, but such logic
was missing from the sun4v DAX code.
