efi: Fix to use null handle to create new handle for efi_fmp_raw
 
When running the efidebug capsule disk-update command, the efi_fmp_raw
protocol installation fails with 2 (EFI_INVALID_PARAMETER) as below.
This is because the code passes efi_root instead of the handle local var.

Command failed, result=1

To fix this issue, pass the handle local var which is set NULL right
before installing efi_fmp_raw as same as the installing efi_fmp_fit.
(In both cases, the local reference to the handle will be just discarded)
