[PATCH 6/7] ext4: use nofail variant of inode_setattr()

[Dmitry Monakhov <dmonakhov@openvz.org>]

After we updated i_disk_size and stop the journal it is
too late for error handling from inode_setattr().
Since inode_change_ok() is now responsible for all
necessery checks we may call __inode_setattr() which can
not fail.
