Cleanup: addReplyAggregateLen and addReplyBulkLen remove redundant check (#8431)

Browse Source 
addReplyLongLongWithPrefix, has a check against negative length, and the code
flow removed in this commit bypasses the check.
addReplyAggregateLen has an assertion for negative length, but addReplyBulkLen
does not, so this commit fixes theoretical case of access violation (probably
unreachable though)
