[dpdk-dev] [PATCH] pdump: remove deprecated APIs

We already changed to use generic IPC in pdump since below commit:

commit 660098d61f57 ("pdump: use generic multi-process channel")

The `rte_pdump_set_socket_dir()`, the `path` parameter of
`rte_pdump_init()` and the `enum rte_pdump_socktype` have been
deprecated since then. This commit removes these deprecated
APIs and also bumps the pdump ABI.
