arm-bsp/u-boot: corstone1000: Disable mm_communicate failure log

Browse Source 
When a getVariable() call is made with data size set to 0,
mm_communicate should return EFI_BUFFER_TOO_SMALL. This is
an expected behavior. There should not be any failure logs
in this case. So the error log is commented here.
