Eric Dumazet 83231e0aae crypto: af_alg - fix possible uninit-value in alg_bind() 
commit a466856e0b7ab269cdf9461886d007e88ff575b0 upstream.

syzbot reported :

BUG: KMSAN: uninit-value in alg_bind+0xe3/0xd90 crypto/af_alg.c:162

We need to check addr_len before dereferencing sa (or uaddr)

Fixes: bb30b8848c85 ("crypto: af_alg - whitelist mask and type")
