crypto: ecdh - move curve_id of ECDH from the key to algorithm name
1. crypto and crypto/atmel-ecc: Move curve id of ECDH from the key into the algorithm name instead in crypto and atmel-ecc, so ECDH algorithm name change form 'ecdh' to 'ecdh-nist-pxxx', and we cannot use 'curve_id' in 'struct ecdh'; 2. crypto/testmgr and net/bluetooth: Modify 'testmgr.c', 'testmgr.h' and 'net/bluetooth' to adapt the modification.
