Mathias Krause ce1abd2563 crypto: user - re-add size check for CRYPTO_MSG_GETALG
commit 055ddaace0 upstream.

Commit 9aa867e465 ("crypto: user - Add CRYPTO_MSG_DELRNG")
accidentally removed the minimum size check for CRYPTO_MSG_GETALG
netlink messages. This allows userland to send a truncated
CRYPTO_MSG_GETALG message as short as a netlink header only making
crypto_report() operate on uninitialized memory by accessing data
beyond the end of the netlink message.

Fix this be re-adding the minimum required size of CRYPTO_MSG_GETALG
messages to the crypto_msg_min[] array.

Fixes: 9aa867e465 ("crypto: user - Add CRYPTO_MSG_DELRNG")
