snort: fix unused result warning for gcc-10
make build-release CC=gcc-10
src/plugins/snort/daq_vpp.c:606:14: error:
ignoring return value of ‘read’ declared with
attribute ‘warn_unused_result’ [-Werror=unused-result]
606 | (void) read (qp->enq_fd, &ctr, sizeof (ctr));
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
gcc void cast cannot suppress __attribute((warn_unused_result)),
use __attribute__((unused)) instead.
Type: fix
Fixes: 839b1473e968 ("snort: snort3 plugin and DAQ")
