nicira-ext: Remove the autopath action.

Browse Source 
The autopath action was attempting to achieve functionality similar
to the bundle action, but was significantly clunkier, more
difficult to understand, more difficult to use, and less reliable.
This patch removes it.

/* Action structure for NXAST_AUTOPATH.
*
* This action performs the following steps in sequence:
*
* 1. Hashes the flow using an implementation-defined hash function.
*
* The hashed fields' values are drawn from the current state of the
* flow, including all modifications that have been made by actions up to
* this point.
*
* 2. Selects an OpenFlow 'port'.
*
* 'port' is selected in an implementation-defined manner, taking into
* account 'id' and the hash value calculated in step 1.
*
* Generally a switch will have been configured with a set of ports that
* may be chosen given 'id'. The switch may take into account any number
* of factors when choosing 'port' from its configured set. Factors may
* include carrier, load, and the results of configuration protocols such
* as LACP.
*
* 3. Stores 'port' in dst[ofs:ofs+n_bits].
*
* The format and semantics of 'dst' and 'ofs_nbits' are similar to those
* for the NXAST_REG_LOAD action.
*
* The switch will reject actions in which ofs+n_bits is greater than the width
* of 'dst', with error type OFPET_BAD_ACTION, code OFPBAC_BAD_ARGUMENT.
