KVM: x86/mmu: Rename handle_removed_tdp_mmu_page() to handle_removed_pt()

First remove tdp_mmu_ from the name since it is redundant given that it
is a static function in tdp_mmu.c. There is a pattern of using tdp_mmu_
as a prefix in the names of static TDP MMU functions, but all of the
other handle_*() variants do not include such a prefix. So drop it
entirely.

Then change "page" to "pt" to convey that this is operating on a page
table rather than an struct page. Purposely use "pt" instead of "sp"
since this function takes the raw RCU-protected page table pointer as an
argument rather than  a pointer to the struct kvm_mmu_page.

No functional change intended.
