tcp: make congestion control optionally skip slow start after idle ...
Congestion control modules that want full control over congestion
control behavior do not want the cwnd modifications controlled by
the sysctl_tcp_slow_start_after_idle code path.
So skip those code paths for CC modules that use the cong_control()
API.
As an example, those cwnd effects are not desired for the BBR congestion
control algorithm.
Fixes: c0402760f565 ("tcp: new CC hook to set sending rate with rate_sample in any CA state")
