We have a global tag refspec structure that is used by both git-clone(1) and git-fetch(1). Initialization of the structure will break once we enable `-Wwrite-strings`, even though the breakage is harmless. While we could just add casts, the structure isn't really required in the first place as we can simply initialize the structures at the respective callsites. Refactor the code accordingly.

/**

* A struct refspec_item holds the parsed interpretation of a refspec. If it

|
|
* (sides end with '*') pattern is true. If it is a negative refspec, (starts
|
|
* with '^'), negative is true. src and dest are the two sides (including '*'
|
|
* characters if present); if there is only one side, it is src, and dst is
|
|
* NULL; if sides exist but are empty (i.e., the refspec either starts or ends
|
|
* with ':'), the corresponding side is "".
