    vboot: TPM2 - report attempts to re-create NVRAM spaces
    
    Currently the tlcl_define_space() function returns the same error
    value for any non-zero TPM response code. The thing is that the caller
    might want to allow attempts to re-create existing NVRAM spaces. This
    patch adds a new API return value to indicate this condition and uses
    it as appropriate.
    
    BRANCH=none
    BUG=chrome-os-partner:59654
    TEST=for test purposes modified the code not to create the firmware
         space, wiped out the TPM NVRAM and booted the device. Observed it
         create kernel and MRC index spaces on the first boot and then
         reporting return code 0x14c for already existing spaces on the
         following restarts.
