KVM: x86/mmu: Decompose kvm_mmu_get_page() into separate functions
Decompose kvm_mmu_get_page() into separate helper functions to increase
readability and prepare for allocating shadow pages without a vcpu
pointer.
Specifically, pull the guts of kvm_mmu_get_page() into 2 helper
functions:
kvm_mmu_find_shadow_page() -
Walks the page hash checking for any existing mmu pages that match the
given gfn and role.
kvm_mmu_alloc_shadow_page()
Allocates and initializes an entirely new kvm_mmu_page. This currently
requries a vcpu pointer for allocation and looking up the memslot but
that will be removed in a future commit.
No functional change intended.
