Sumit Garg 91e94e42f6 tee: optee: Fix incorrect page free bug ...

commit 18549bf4b2 upstream.

Pointer to the allocated pages (struct page *page) has already
progressed towards the end of allocation. It is incorrect to perform
__free_pages(page, order) using this pointer as we would free any
arbitrary pages. Fix this by stop modifying the page pointer.

Fixes: ec185dd3ab ("optee: Fix memory leak when failing to register shm pages")
