[PATCH v2 2/5] fs: fiemap: update fiemap_fill_next_extent() signature

[Sweet Tea Dorminy <sweettea-kernel@dorminy.me>]

Update the signature of fiemap_fill_next_extent() to allow passing a
physical length. Update all callers to pass a 0 physical length -- since
none set the EXTENT_HAS_PHYS_LEN flag, this value doesn't matter.
