Here are two patches for ecdsa to avoid reporting nonsensical values
for enc/dec size and -- for P521 keys -- also the key size in response
to KEYCTL_PKEY_QUERY system calls.

Resending as requested by Herbert:

Although these are technically fixes, the issues they address are
not critical, so I recommend not applying as fixes for v6.15,
but rather let the patches soak in linux-next for v6.16.
