Fix netmask handling in inet_minmax_multi_ops When calculating distance in brin_minmax_multi_distance_inet(), the netmask was applied incorrectly. This results in (seemingly) incorrect ordering of values, triggering an assert.
For builds without asserts this is mostly harmless - we may merge other ranges, possibly resulting in slightly less efficient index. But it's still correct and the greedy algorithm doesn't guarantee optimality anyway. Backpatch to 14, where minmax-multi indexes were introduced. Reported by Dmitry Dolgov, investigation and fix by me.
