resolve_gitlink_packed_ref(): fix mismerge

2c5c66b (Merge branch 'jp/get-ref-dir-unsorted', 2011-10-10) merged a
topic that forked from the mainline before a new helper function
get_packed_refs() refactored code to read packed-refs file. The merge made
the call to the helper function with an incorrect argument. The parameter
to the function has to be a path to the submodule.

Fix the mismerge.
