[PATCH v2 0/2] Add wrapper to read GPR of INVPCID, INVVPID, and INVEPT

[Vipin Sharma <vipinsh@google.com>]

Hello,

VMX code to handle INVPCID, INVVPID, and INVEPT read the same GPR index
in VM exit info. This patch series improves that handling by adding a
common wrapper function for them.

This series also moves INVPCID type check from both SVM and VMX to
common place in kvm_handle_invpcid().

Overall, this series is just reducing duplicate code.

Changes in v2:
- Keeping the register read visible in the functions.
- Removed INVPCID type check hardcoding and moved error condition to common 
  function.
