[PATCH] mm: return ENOBUFS instead of ENOMEM in generic_file_buffered_write

As noticed by Dmitry Torokhov, write() can not return ENOMEM:

http://www.opengroup.org/onlinepubs/000095399/functions/write.html

Therefore fixup generic_file_buffered_write() in mm/filemap.c (pointed out by
Nathan Scott).
