Denis Kenzior 10de7b5429 KEYS: asymmetric: Fix ECDSA use via keyctl uapi 
When support for ECDSA keys was added, constraints for data & signature
sizes were never updated.  This makes it impossible to use such keys via
keyctl API from userspace.

Update constraint on max_data_size to 64 bytes in order to support
SHA512-based signatures. Also update the signature length constraints
per ECDSA signature encoding described in RFC 5480.

Fixes: 299f561a66 ("x509: Add support for parsing x509 certs with ECDSA keys")
