feat: merge dummy entry of transfer list

When transfer_list_set_data_size() is called in sequence—first to
shrink an entry, then to expand it—the dummy entry created during
the shrink is not reused in the expansion.

This leaves unused dummy entries that increase the total size of
the transfer list unnecessarily.

This patch addresses that by:

  1. Reusing a following dummy entry when expanding
     the size of a transfer list entry.

  2. Merging adjacent dummy entries when removing an entry,
     reducing fragmentation and improving reuse.
