ext4: track partial-zero outcome per edge in ext4_zero_partial_blocks()

Replace the single bool did_zero output of ext4_zero_partial_blocks()
with a bitmask that records which edge (start, end, or both in the
single-block case) was actually partial-zeroed. This allows callers to
distinguish which edges have been zeroed, preparing for unaligned
FALLOC_FL_WRITE_ZEROES handling in later patches.
