IPVS: ip_vs_sync.c: local functions should not be exposed globally

Functions not referenced outside of a source file should be marked
static to prevent it from being exposed globally.

This quiets the sparse warnings:

warning: symbol 'ip_vs_sync_conn_v0' was not declared. Should it be static?

	The 3 patches for IPVS look correct but this change
is already not needed after one of our planned changes:

"ipvs: reduce sync rate with time thresholds"

	Not sure how we will avoid the collision, may be
Simon will take only the other 2 changes? Or David will
take all changes and we have to rebase?

I think the best way forwards is for me to take only the first two changes.

I don't think that this fix is 3.4 material and as you say we expect this
problem to be resolved by other means in 3.5.

I am of course open to discussion on this.
