Fix rare bug in read_stream.c's split IO handling.HEADorigin/masterorigin/HEADmaster
The internal queue of buffers could become corrupted in a rare edge case
that failed to invalidate an entry, causing a stale buffer to be
"forwarded" to StartReadBuffers(). This is a simple fix for the
immediate problem.
A small API change might be able to remove this and related fragility
entirely, but that will have to wait a bit.
Defect in commit ed0b87ca.
