nfs: Replace kmap() with kmap_local_page()
The use of kmap() is being deprecated in favor of kmap_local_page().
With kmap_local_page(), the mapping is per thread, CPU local and not
globally visible. Furthermore, the mapping can be acquired from any context
(including interrupts).
Therefore, use kmap_local_page() in nfs_do_filldir() because this mapping
is per thread, CPU local, and not globally visible.
