Fixed compiler warnings & failing test cases

When compiling with debug, don't clear buffer in 'net_clear()'
- This allows us to easier find bugs in the protocol and also get repeatable test failures in test cases where someone forgot to do --reap

client/mysqltest.cc:
  Fixed compiler warning
mysql-test/t/partition_innodb_semi_consistent.test:
  Added missing --reap (fixes random failure)
