8d35d8752b instr_emul: remove vm_gva2gpa
- vm_gva2gpa is same as gva2gpa, so replace it with gva2gpa directly.
- remove dead usage of vm_gva2gpa in emulate_movs.

570aef648a instr_emul: refine decode_instruction with copy_from_gva
use copy_from_gva in vie_init, if copy_from_gva meet -EFAULT, inject #PF.
And for decode_instruction, if return -EFAULT, the caller should keep return
path with successful status.

v2:
- remove vm_restart_instruction when inject #PF

11d0e59b3e revise type of 'exit_reason' and 'inst_len' in vcpu_arch
SDM 24.9.1 Volume3:
 - 'Exit reason' field in VMCS is 32 bits.

 SDM 24.9.4 in Volume3
 - 'VM-exit instruction length' field
   in VMCS is 32 bits.

 This patch is to redefine the data types of above fields
 in 'struct vcpu_arch' and udpate the code using these
 two fields.
