Explain what this test is doing, and check that the decoded action can
be re-encoded and dumped back out of OVS.

dnl Bundle actions with <= 2 ports typically align nicely within ofpbuf memory
dnl allocation, so will not trigger reallocation codepaths. This test was
dnl introduced to ensure that when bundle actions with a larger number of ports
dnl are used, the encode/decode still works correctly. By placing the bundle
dnl action deep within a list of actions, this test was able to trigger
dnl Valgrind warnings for use-after-free bugs.
