fs/ext2: Replace kmap_atomic() with kmap_local_page()
kmap_atomic() is deprecated in favor of kmap_local_page(). Therefore,
replace kmap_atomic() with kmap_local_page().
kmap_atomic() is implemented like a kmap_local_page() which also disables
page-faults and preemption (the latter only for !PREEMPT_RT kernels).
However, the code within the mapping and un-mapping in ext2_make_empty()
does not depend on the above-mentioned side effects.
Therefore, a mere replacement of the old API with the new one is all it
is required (i.e., there is no need to explicitly add any calls to
pagefault_disable() and/or preempt_disable()).
