[pve-devel] [PATCH manager] fix 'NaN%' when max value is 0

[Dominik Csapak]

when we get a max value of 0
(for example when a storage is not active)

the render function would show:
'NaN% (0B of 0B)'

because of a division by 0

this patch simply returns 'N/A' because
a max value of 0 should never be valid
