rte_free accepts only non-cva qualified arguments so cast away
RTE_ATOMIC qualification for tbl_chng_cnt and h->tbl_chng_cnt when
calling rte_free.

Please add an explanation about the case where it does not compile.

rte_free accepts only non-cva qualified arguments so cast away
RTE_ATOMIC qualification for tbl_chng_cnt and h->tbl_chng_cnt when
calling rte_free.
Without this change using enable_stdatomic=true with LLVM or MSVC will
result in a warning being emitted for discarding the atomic
qualification.
v2:
* update commit message to indicate the conditions under
which a warning will be issued without this patch.
