[cudaaligner] Disabled caching device-allocator may trigger OOM in cudaaligner

[ahehn-nv]

AlignerGlobalMyersBanded's reset_max_bandwidth(...) runs out of device memory when the caching device-allocator is disabled at compilation. (This allocator is enabled by default.) It is unclear if cudaaligner respects the max_device_memory setting passed at construction at all in this case.
