Jesper Dangaard Brouer 7bd4224dee selftests/bpf: xdp_hw_metadata correct status value in error(3)
The glibc error reporting function error():

 void error(int status, int errnum, const char *format, ...);

The status argument should be a positive value between 0-255 as it
is passed over to the exit(3) function as the value as the shell exit
status. The least significant byte of status (i.e., status & 0xFF) is
returned to the shell parent.

Fix this by using 1 instead of -1. As 1 corresponds to C standard
constant EXIT_FAILURE.
