[PATCH v5 05/13] refs/files: remove unused "skip" in lock_raw_ref() too

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Remove the unused "skip" parameter to lock_raw_ref(), it was never
used. We do use it when passing "skip" to the
refs_rename_ref_available() function in files_copy_or_rename_ref(),
but not here.

This is part of a larger series that modifies lock_ref_oid_basic()
extensively, there will be no more modifications of this function in
this series, but since the preceding commit removed this unused
parameter from lock_ref_oid_basic(), let's do it here too for
consistency.
