Move errbuf from file scope to local variables in the two functions that use it (open_iface_live and open_single_rx_pcap). This avoids potential issues if these functions were called concurrently, since each call now has its own error buffer. Move iface_idx to a static local variable within pmd_init_internals(), the only function that uses it. The variable remains static to preserve the MAC address uniqueness counter across calls.
