[PATCH v3 2/4] t-reftable-readwrite: use free_names() instead of a for loop

[Chandra Pratap <chandrapratap3519@gmail.com>]

free_names() as defined by reftable/basics.{c,h} frees a NULL
terminated array of malloced strings along with the array itself.
Use this function instead of a for loop to free such an array.
