bdev/crypto: separate out search for vbdev_dev

Browse Source 
This patch is first in series that updates bdev crypto
to support DPDK 22.11. See changelog entry from DPDK:
* cryptodev: The structure ``rte_cryptodev_sym_session`` was made internal.
  The API ``rte_cryptodev_sym_session_init`` and
``rte_cryptodev_sym_session_clear``
  were removed and user would only need to call
``rte_cryptodev_sym_session_create``
  and ``rte_cryptodev_sym_session_free`` to create/destroy sessions.
  The API ``rte_cryptodev_sym_session_create`` was updated to take a single
mempool
  with element size big enough to hold session data and session private
data.

So this patch abstracts out lookup for vbdev_dev as it will be used from
multiple places later in the series.
