[PATCHv9 2/9] receive-pack.c: move iterating over all commands outside execute_commands

[Stefan Beller <sbeller@google.com>]

This commit allows us in a later patch to easily distinguish between
the non atomic way to update the received refs and the atomic way which
is introduced in a later patch.

Notes:
    v9:
     new and shiny. But makes the next patch easier to review.
