MN10300: Change the fault handler to check in_atomic() not in_interrupt()
Change the MN10300 fault handler to make it check in_atomic() rather than
in_interrupt() as commit 6edaf68a87d17570790fd55f0c451a29ec1d6703 did for other
architectures:

[PATCH] mm: arch do_page_fault() vs in_atomic()
In light of the recent pagefault and filemap_copy_from_user work I've
gone through all the arch pagefault handlers to make sure the
inc_preempt_count() 'feature' works as expected.
Several sections of code (including the new filemap_copy_from_user)
rely on the fact that faults do not take locks under increased preempt
count.
