This is a follow up commit to 74328ee which correctly resolved a lock inversion between zfs_putpage() and zfs_free_range(). Unfortunately, in the process it accidentally introduced another inversion between zfs_putpage() and zfs_read(). The page must be unlocked before taking the range lock. This patch corrects that issue. In addition, because the locking rules here are subtle a block comment has been added clearly explaining why the ordering here is critical.
