Daniele Alessandrelli 19ba58ec46 crypto: ecdh_helper - Ensure 'len >= secret.len' in decode_key() 
[ Upstream commit a53ab94eb6850c3657392e2d2ce9b38c387a2633 ]

The length ('len' parameter) passed to crypto_ecdh_decode_key() is never
checked against the length encoded in the passed buffer ('buf'
parameter). This could lead to an out-of-bounds access when the passed
length is less than the encoded length.

Add a check to prevent that.
