[ Upstream commit8d3c1fa3fa] When testing with a mixed zoned / convention device combination, there are regular but not 100% reproducible failures in xfstests generic/113 where the __is_valid_data_blkaddr assert hits due to finding a hole. This seems to be because f2fs_map_blocks can set this flag on a hole when it was found in the extent cache. Rework f2fs_iomap_begin to just check the special block numbers directly. This has the added benefits of the WARN_ON showing which invalid block address we found, and being properly error out on delalloc blocks that are confusingly called unwritten but not actually suitable for direct I/O.
