When specifying -C for multithread mode, we calculate a 'blocks_per_job' to tell each core what subset of the bdev it should target with I/O. But this blocks_per_job, and the config->length member that it gets copied to, were ints. For devices with num blocks > INT32_MAX, this can cause overflow if the num blocks is also < UINT32_MAX (because then we end up storing a negative value in the bdevperf's length field). For sequential workloads, it may take a long time until it happens, but for random workloads it fails almost immediately. Fixes issue #2108.
