zbd/008: check no stale page cache after BLKRESETZONE ioctl

Run two processes which repeat data read and BLKRESETZONE ioctl, and
check that the race does not leave stale page cache. This allows to
catch the bug fixed with the commit e5113505904e ("block: Discard page
cache of # zone reset target range").
