IMPALA-5261: Heap use-after-free in HdfsSequenceTableWriter

HdfsSequenceTableWriter::ConsumeRow() function dereferenced a pointer
that pointed to a previously deallocated memory (which belonged to an
out of scope string object). This caused the ASAN build to fail.

The fix was verified by running TestTableWriters.test_seq_writer and
TestTableWriters.test_seq_writer_hive_compatibility end-to-end tests
against the ASAN build. These tests consistently crashed impalad
before the fix.
