ext4: make ext4_ind_map_blocks work with fiemap
For indirect block mapping if the i_block > max supported block in inode
then ext4_ind_map_blocks() returns a -EIO error. But in case of fiemap
this could be a valid query to ->iomap_begin call.
So check if the offset >= s_bitmap_maxbytes in ext4_iomap_begin_report(),
then simply skip calling ext4_map_blocks().
