btrfs/163: make readahead run on the seed device
There is a long lived bug that btrfs wait for readahead to finish
indefinitely when readahead zone is inserted into seed devices.
Current write size to the file "foobar" is too small to run readahead
before the replacing on seed device. So, increase the write size to
reproduce the issue.
Following patch fixes it:
"btrfs: start readahead also in seed devices"
