core: fix tee_pager_release_one_phys() assert Prior to this patch it was assumed in tee_pager_release_one_phys() that a locked fobj would not span multiple page directories. This is not correct since it depends on the base address and size of the locked fobj. If the base address is close to the end of a page directory it can very well happen. With CFG_CORE_ASLR=y this is bound to happen sooner or later even if everything seems to work with CFG_CORE_ASLR=n. This patch fixes this by instead counting the number of areas which uses the pmem to be released. The number should be exactly one.
