Fix expanding 'bounds' in pg_trgm's calc_word_similarity() function If the 'bounds' array needs to be expanded, because the input contains more trigrams than the initial guess, the code didn't return the reallocated array correctly to the caller. That could lead to a crash in the rare case that the input string becomes longer when it's lower-cased. The only known instance of that is when an ICU locale is used with certain single-byte encodings. This was an oversight in commit 00896ddaf41f.
