Artem Bityutskiy 4bc1dca4b0 UBI: fix mean EC calculation ...

(a + b) / (c + d) != a / c + b / d. The old code errornously
assumed this incorrect formuld. Instead, just sum all erase
counters in a 64-bit variable and divide to the number of EBs
at the end.

Thanks to Adrian Hunter for pointing this out.
