Skip registering erase blocks protocol if storage type is not virtual

We only initialize erase blocks in virtual storage case, since there is
no callback function for other storage types(mmc, ufs and nvme).Otherwise
it will bring out "EFI_ERASE_BLOCK_PROTOCOL failed to erase block"
error log while erasing.
