KVM: nVMX: Also filter MSR_IA32_VMX_TRUE_PINBASED_CTLS when eVMCS

[ Upstream commit f80ae0ef089a09e8c18da43a382c3caac9a424a7 ]

Similar to MSR_IA32_VMX_EXIT_CTLS/MSR_IA32_VMX_TRUE_EXIT_CTLS,
MSR_IA32_VMX_ENTRY_CTLS/MSR_IA32_VMX_TRUE_ENTRY_CTLS pair,
MSR_IA32_VMX_TRUE_PINBASED_CTLS needs to be filtered the same way
MSR_IA32_VMX_PINBASED_CTLS is currently filtered as guests may solely rely
on 'true' MSR data.

Note, none of the currently existing Windows/Hyper-V versions are known
to stumble upon the unfiltered MSR_IA32_VMX_TRUE_PINBASED_CTLS, the change
is aimed at making the filtering future proof.
