[dpdk-dev] [PATCH v3 2/2] test/rcu: address test case failure

[Honnappa Nagarahalli <honnappa.nagarahalli@arm.com>]

Test case for rte_rcu_qsbr_get_memsize is written specifically
for 128 threads. Do not use RTE_MAX_LCORE as it changes for
different configurations.

Fixes: e6a14121f4ae ("test/rcu: remove arbitrary limit on max core count")
