While compiling the spsc_q unit tests on some compilers, some
complain with
/openairinterface5g/common/utils/ds/tests/test_spsc_q.cpp:11:44: error: use of deleted function ‘spsc_q::spsc_q(spsc_q&&)’
spsc_q_t rb = spsc_q_alloc(2, sizeof(int));
/openairinterface5g/common/utils/ds/spsc_q.h:19:16: error: use of deleted function ‘std::atomic<long unsigned int>::atomic(const std::atomic<long unsigned int>&)’
These compiles cannot copy the atomic. Change the API to avoid this
copy.
"Older" compiler here means g++-11/12.
