tools/hv: Fix exit() error code
Linux native exit codes are 8-bit unsigned values. exit(-1) results in an exit code of 255, which is usually reserved for shells reporting 'command not found'. Use the portable value EXIT_FAILURE. (Not that this matters much for a daemon.) Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: K. Y.
