On 32-bit platforms, the computed size of the BIO_SPEEDUP requested by softdep_request_cleanup() may be negative when assigned to bp->b_bcount, which has type "long". Clamp the size to LONG_MAX. Also convert the unused g_io_speedup() to use an off_t for the magnitude of the shortage for consistency with softdep_send_speedup().
