avr32: Fix oops on unaligned user access
The unaligned address exception handler (and others) does not scan the fixup tables before oopsing. This is bad because it means passing a badly aligned pointer from user space might crash the kernel. Fix this by scanning the fixup tables in _exception(). This should resolve the issue for unaligned addresses as well as other less common exceptions that might be happening during a userspace access. The page fault handler already does fixup processing.
