[PATCH v3 1/9] promisor-remote: refactor initialising field lists

[Christian Couder <christian.couder@gmail.com>]

In "promisor-remote.c", the fields_sent() and fields_checked()
functions serve similar purposes and contain a small amount of
duplicated code.

As we are going to add a similar function in a following commit,
let's refactor this common code into a new initialize_fields_list()
function.
