ext4: no need to truncate pagecache twice in collapse range
We're already calling truncate_pagecache() before we attempt to do any actual job so there is not need to truncate pagecache once more using truncate_setsize() after we're finished. Remove truncate_setsize() and replace it just with i_size_write() note that we're holding appropriate locks.
