crypto: user - fix memory leak in crypto_reportstat
commit c03b04dcdba1da39903e23cc4d072abf8f68f2dd upstream.
In crypto_reportstat, a new skb is created by nlmsg_new(). This skb is
leaked if crypto_reportstat_alg() fails. Required release for skb is
added.
Fixes: cac5818c25d0 ("crypto: user - Implement a generic crypto statistics")
