Mikhail Zaslonko e35d05a5e3 zipl/boot: Add print_progress parameter to write_addr_range()
With current implementation, printing progress while writing a compressed
data chunk might be very inaccurate. Thus, for compressed dump segments
skip progress_print() in write_addr_range() and call it after each
compressed memory chunk is written to disk. For that change
write_addr_range() to call progress_print() conditionally based on the new
print_progress parameter.

For non-compressed dump segments, call progress_print() from
write_addr_range() just as before.
