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]
