examples: genl: fix wrong attribute size

This example no longer works on more recent kernels:

genl-family-get
error: Invalid argument

dmesg says:
netlink: 'genl-family-get': attribute type 1 has an invalid length.

Fix this and also zero out the reserved field in the genl header,
while not validated yet for dumps this could change.
