* string.c (rb_fstring, fstr_update_callback): simply delete garbage
key first.
Garbage keys can be swept by lazy sweeping invoked by creating new
fstring. So that simply do:
(1) delete garbage key and return `fstr_update_callback' immediately
(2) try again `fstr_update_callback()' to create a new fstr.
This bug can be cause memory corruption, reported by
