[v5,2/6] fetch-pack: move fetch initialization

Commit Message

Calvin Wan July 28, 2022, 11:02 p.m. UTC

There are some variables that are initialized at the start of the
do_fetch_pack_v2() state machine. Currently, these are initialized
in FETCH_CHECK_LOCAL, which is the initial state set at the beginning
of the function.

However, a subsequent patch will allow for another initial state,
while still requiring these initialized variables. Therefore, move
the initialization to before the state machine, so that they are set
regardless of the initial state.

Note that there is no change in behavior, because we're moving code
from the beginning of the first state to just before the execution of
the state machine.
