1. Fix some potential uninitialized pointer errors in the functions sp_RsaPublic_2048, sp_RsaPublic_3072, and sp_RsaPublic_4096 for small stack builds.

To recreate:
    $ scan-build ./configure --enable-sp=small --enable-smallstack --enable-smallstackcache CPPFLAGS="-DECC_CACHE_CURVE -DHAVE_WOLF_BIGINT"
