[PATCH v6 1/6] worktree: remove extra members from struct add_opts

[Thomas Gummerer <t.gummerer@xxxxxxxxx>]

There are two members of 'struct add_opts', which are only used inside
the 'add()' function, but being part of 'struct add_opts' they are
needlessly also passed to the 'add_worktree' function.

Make them local to the 'add()' function to make it clearer where they
are used.
