[OE-core] [PATCH 4/6] devtool: update-recipe: fix --initial-rev option

[Paul Eggleton]

In OE-Core revision 7baf57ad896112cf2258b3e2c2a1f8b756fb39bc I changed
the default update-recipe behaviour to only update patches for commits
that were changed; unfortunately I failed to handle the --initial-rev
option which was broken after that point. Rework how the initial
revision is passed in so that it now operates correctly.
