Fix warn message and update man page

Fix regression in man page. The chunk size is in kilobyte units on command line
input though in the source code we work with sector size unit
so make it clear in the man page.

Update chunksize for thin pool in man page - it's max value is 1024M == 1G.

Fix warning range message to show proper max value.
