    net/bnxt: fix free of not allocated object

    This was found as error when compiling with LTO.
    The function allocates new data with rte_zmalloc and then
    stores pointer in the pointer-to-pointer passed as argument.
    In the unwind case, it would call rte_free() with wrong one.

    Fixes: 80317ff6adfd ("net/bnxt/tf_core: support Thor2")
