KVM: MMU: fix bogus alloc_mmu_pages assignment
(cherry picked from commit b90c062c65cc8839edfac39778a37a55ca9bda36)
Remove the bogus n_free_mmu_pages assignment from alloc_mmu_pages.
It breaks accounting of mmu pages, since n_free_mmu_pages is modified
but the real number of pages remains the same.
