net: tls: fix returned read length with async decrypt

Browse source 
We double count async, non-zc rx data. The previous fix was
lucky because if we fully zc async_copy_bytes is 0 so we add 0.
Decrypted already has all the bytes we handled, in all cases.
We don't have to adjust anything, delete the erroneous line.
