Fix for BUG#9814: Clear thd->net.no_send_error before each SP instruction

execution. Failure to do so caused the erroneous statements to send nothing
and hang the client.


mysql-test/r/sp-error.result:
  Testcase for BUG#9814. Note that the result demonstrates that currently
  mysql-test-run ignores errors in multi-statement if they arrive after first 
  resultset has been received.
mysql-test/t/sp-error.test:
  Testcase for BUG#09814.
