[network-data] limit router upgrade delay when registering (#6613)

Browse Source 
If a device is a REED and waiting the random delay to upgrade to a
router, the device will wait to register its network data, since it
will have to register again after upgrading to a router. However, the
maximum delay for becoming a router is up to 2 minutes, which is a
long time to wait.

This commit limits the delay that a device will wait to register its
network data.
