erts: Fix bug in ets:update_counter causing wrong table size
if
* called on 'set' table
* with 4th argument Default
* Key does not exist in table
* operation fails due to invalid UpdateOp.
Table size counter would be falsely decremented
which could make ets:info(T,size) return a negative value or
an absurd large value.
Bug introduced in OTP-19.0.2 by
a6d87854c3ae65dba8dba6571b4d31d901316a39.
