drm/ttm: Merge hugepage attr changes in ttm_dma_page_put. (v2)
Every set_pages_array_wb call resulted in cross-core
interrupts and TLB flushes. Merge more of them for
less overhead.
This reduces the time needed to free a 1.6 GiB GTT WC
buffer as part of Vulkan CTS from ~2 sec to < 0.25 sec.
(Allocation still takes more than 2 sec though)
(v2): use set_pages_wb instead of set_memory_wb.
