* volume server: do not finish a GET when the needle CRC mismatches
A streamed full-needle read compared the CRC only after every page had been written. Once the response buffer flushed, the client already had a completed 200 and the corrupt bytes. Hold the last page until the checksum matches, and if an earlier page has already been flushed, abort the connection instead of calling http.Error.
Fixes#11459
* volume server: abort partial-content bodies on write error too
The non-Range path drops the unflushed tail and aborts on a mid-body
error; the single-range and multi-range paths still flushed it after
WriteHeader(206) was committed, delivering corrupt bytes as a complete
body.

* volume server: assert the started 200 is aborted in the write-error test
The test previously returned on any request error, so it passed without
verifying the abort. It now asserts the client got the committed 200
headers and then a failed body read. Also trims comments.
