[dpdk-dev] [PATCH v1] app/test: zcd needs to be initialised to fix gcc compile error

[Conor Walsh <conor.walsh@intel.com>]

When DPDK is compiled with gcc < 9 with the optimization level set to 1
gcc sees zcd in test_ring.h as possibly being uninitialised. To correct
this error zcd has been initialised to {0} in
test_ring_mt_peek_stress_zc.c.
