net: tls: fix returned read length with async decrypt
[ Upstream commit ac437a51ce662364062f704e321227f6728e6adc ]
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.
Fixes: 4d42cd6bc2ac ("tls: rx: fix return value for async crypto")
