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.
