[PATCH v2] crypto/ipsec_mb: expect ENOTSUP

[Krzysztof Karas <krzysztof.karas@intel.com>]

Commit b35848bc01f6 ("crypto/ipsec_mb: add multi-process
IPC request handler") is part of DPDK 22.11 release and
it enforces usage of shared config and multiprocess mode.

DPDK is not required to be run with more than one
process in general, so instead of erroring out,
catch the error and proceed with ipsec_mb device
creation normally.

Fixes: b35848bc01f6 ("crypto/ipsec_mb: add multi-process IPC request handler")
