Display progress for what is actually erased/written

The patch updates calculation of total length for the operation
which is displayed with progress.

The reason is: even if, for example the whole chip erase or write
was requested, the actual length of bytes modified can be less than
whole chip size (areas which already have expected content,
are skipped).
