It used to check each page in the readahead window is covered by
a lock underneath, now cpo_page_is_under_lock() provides @max_index
to help decide the maximum ra window. @max_index can be modified by
OSC to extend the maximum lock region, to align stripe boundary at
LOV, and to make sure the readahead region at least covers read
region at LLITE layer.
After this is done, usually readahead code calls
cpo_page_is_under_lock() for each stripe.

This reverts a patch that was merged before lustre client
was introduced into the stagign tree, so it's not in the history.
The performance dropped a lot when memory reclaim process kicked
in as ll_releasepage() was called to destroy lustre pages. It turned
out that big overhead to allocate cl_env and keys on the fly so we
have to revert this patch.
The original problem for the reverted patch would be solved in a
follow on patch instead.
