crypto: af_alg - Fix regression on empty requests
commit 662bb52f50bca16a74fe92b487a14d7dccb85e1a upstream.
Some user-space programs rely on crypto requests that have no
control metadata. This broke when a check was added to require
the presence of control metadata with the ctx->init flag.
This patch fixes the regression by setting ctx->init as long as
one sendmsg(2) has been made, with or without a control message.
