[PATCH] lib/ts_bm.c: remove redundant store to variable consumed after addition

[Colin Ian King <colin.i.king@gmail.com>]

There is no need to store the result of the addition back to variable
consumed after the addition. The store is redundant, replace += with
just +

Cleans up clang scan build warning:
lib/ts_bm.c:83:11: warning: Although the value stored to 'consumed' is
used in the enclosing expression, the value is never actually read
from 'consumed' [deadcode.DeadStores]
