[dpdk-dev] [PATCH 1/2] bus/dpaa: fix build with gcc 9.0

[Ferruh Yigit]

build error:
In function ‘fman_if_init’,
    .../drivers/bus/dpaa/base/fman/fman.c:186:2:
    error: ‘strncpy’ output may be truncated copying 4095 bytes from a
           string of length 4095 [-Werror=stringop-truncation]
    strncpy(__if->node_path, dpa_node->full_name, PATH_MAX - 1);

strncpy may result a not null-terminated string,
replaced it with rte_strscpy
