crypto: scomp - Fix wild memory accesses in scomp_free_streams
In order to use scomp_free_streams to free the partially allocted
streams in the allocation error path, move the alg->stream assignment
to the beginning. Also check for error pointers in scomp_free_streams
before freeing the ctx.
Finally set alg->stream to NULL to not break subsequent attempts
to allocate the streams.
Fixes: 3d72ad46a23a ("crypto: acomp - Move stream management into scomp layer")
