dpdk/crypto: increase RTE_CRYPTO_MAX_DEVS to fit QAT SYM and ASYM VFs



The QAT crypto devices can expose two types of crypto devices,
symmetric (sym) and asymmetric (asym), for each Virtual Function (VF).
The DPDK QAT PMD recommends adjusting the RTE_CRYPTO_MAX_DEVS to
accommodate different scenarios.

Currently, the maximum limit is set to 64 devices. This limit is only
sufficient for 2 QAT devices that expose 16 VFs, each with 2 PMD
devices (sym and asym). However, this limit is exceeded in the
SPDK Jenkins CI environment, necessitating an increase in this value.

This change is related to issue #2258.
