Remove some redundant NetLog info in SpdySession.

This CL removes information (stream id, associated stream id, URL,
window_size) from NetLog strings that can always be inferred from
previous NetLog entries.  RST_STREAM frames cannot carry any opaque
data, therefore the affected strings never make it to the wire, they are
only recorded in NetLog.  Since NetLog is not running most of the time,
it is a waste to call StringPrintf() to generate strings that are unused
most of the time.

String arguments of CloseSessionOnError() and DoDrainSession() are not
changed, since those are sent in GOAWAY frames, and therefore allow
server operators to understand why the client closes the connection.
