[dpdk-dev] [PATCH v2] testpmd: limit port mask bits to RTE_MAX_ETHPORTS

The port mask parsing in testpmd allowed up to 64 bits to be processed,
even if RTE_MAX_ETHPORTS is set to a max of 32. Fix this by only
processing up to min(RTE_MAX_ETHPORTS,64) bits of the mask.

V2: changed to use RTE_MIN in comparison, instead of double "<".
