QUIC: fixed in-flight bytes accounting.
Initially, frames are genereated and stored in ctx->frames.
Next, ngx_quic_output() collects frames to be sent in in ctx->sending.
On failure, ngx_quic_revert_sned() returns frames into ctx->frames.
On success, the ngx_quic_commit_send() moves ack-eliciting frames into
ctx->sent and frees non-ack-eliciting frames.
This function also updates in-flight bytes counter, so only actually sent
frames are accounted.
The counter is decremented in the following cases:
- acknowledgment is received
- packet was declared lost
- we are discarding context completely
In each of this cases frame is removed from ctx->sent queue and in-flight
counter is accordingly decremented.
The patch fixes the case of discarding context - only removing frames
from ctx->sent must be followed by in-flight bytes counter decrement,
otherwise cg->in_flight could experience type underflow.
The issue appeared in b1676cd64dc9.
