api: never return EOF from Logs error chan
api: never return EOF from Logs error chan

Closing the frames chan is the only race-free way to signal to receivers
that all frames have been sent and no errors have occurred.

If EOF is sent on error chan receivers may not receive the last frame
(or frames since the chan is buffered) before receiving the error.

Closing frames is the idiomatic way of signaling there is no more data
to be read from a chan.
