[PATCH] refs.h: rename submodule arguments to submodule_path

[Stefan Beller <sbeller@google.com>]

In submodule land we carefully need to distinguish between the path of a
submodule and its name.

The path of a submodule is the path that is recorded in the working tree
of the superproject and describes where the submodule is bound to the
superprojects tree.

The name as introduced in 941987a554 (git-submodule: give submodules
proper names, 2007-06-11) exists to track submodules across renames of
submodules. It is also used for the internal path in .git/modules/<name>
to store the git directory of the submodule inside the superproject.

When looking up ref functions to use, I was confused which of the two
submodule properties are meant in the argument of the ref functions.
The context in which the functions were used however revealed it is the
path of the submodules.

Rename the arguments to clearly describe what is expected as an input
argument.
