KVM: x86: remove "full" out-argument from flush_tlb_gva
The "full" out-argument in flush_tlb_gva is only ever set on AMD
processors, where the TLB flush is little more than a memory write and
thus extremely cheap anyway.
Simplify the code by letting the implementation of Hyper-V TLB flush
hypercalls always go through all the addresses queued in tlb_flush_fifo;
there are no performance concerns since that is already the case on
VMX, and also was on SVM prior to commit 26505e1b5b54 ("KVM: SVM: make
svm_flush_tlb_gva do a full asid flush if NPT enabled", 2026-08-06).
