Use truncate_setsize in zfs_setattr
According to Linux kernel commit 2c27c65e, using truncate_setsize in
setattr simplifies the code. Therefore, the patch replaces the call
to vmtruncate() with truncate_setsize().
zfs_setattr uses zfs_freesp to free the disk space belonging to the
file. As truncate_setsize may release the page cache and flushing
the dirty data to disk, it must be called before the zfs_freesp.
