mtd-utils: flash_erase: Fix output of offsets

Need to use unsigned arithmetic and a 64-bit cast in order to
calculate and output the correct offset for eraseblocks at large
offsets. Signed integer arithmetic does not produce the correct
result "uint64_t" result, so for offsets over 2GB we get
messages like:

	Erasing 512 Kibyte @ ffffffff83180000 -- 4308642136 % complete.

Note that this error was not affecting proper erasure; it just
produced incorrect status messages.

Also, we should not add an extra eraseblock for the final status
message; this gives misleading output when, for example, the
following statement is executed:

	$ flash_erase /dev/mtd0 0 1
	Erasing 512 Kibyte @ 80000 -- 100 % complete

We aren't erasing at offset 0x80000; it should display offset 0.
