[PATCH] ref-filter.c: fix a leak in get_head_description

In 2708ce62d2 (branch: sort detached HEAD based on a flag, 2021-01-07) a call to wt_status_state_free_buffers, responsible of freeing the resources that could be allocated in the local struct wt_status_state state, was eliminated.

The call to wt_status_state_free_buffers was introduced in 962dd7ebc3 (wt-status: introduce wt_status_state_free_buffers(), 2020-09-27). This commit brings back that call in get_head_description.
