Fix param list of test_mmx_movq_mf and test_movabs. The previous
version uses insn_page and insn_ram which are not used afterwards.
There are also two variants named insn_page and insn_ram, which
has no relation with these two functions.

However, it fails to initialize padding

In commit e935b8372cf8 (KVM: Convert kvm_lock to raw_spinlock),
the kvm_lock was made a raw lock. However, the kvm mmu_shrink()
function tries to grab the (non-raw) mmu_lock within the scope of
the raw locked kvm_lock being held. This leads to the following:
