Subject: crypto: api - permit users to specify numa node of acomp hardware

For a Linux server with NUMA, there are possibly multiple (de)compressors
which are either local or remote to some NUMA node. Some drivers will
automatically use the (de)compressor near the CPU calling acomp_alloc().
However, it is not necessarily correct because users who send acomp_req
could be from different NUMA node with the CPU which allocates acomp.

Just like kernel has kmalloc() and kmalloc_node(), here crypto can have
same support.
