efi_loader: refactor efi_open_protocol
efi_open_protocol was implemented to call a protocol specific open
function to retrieve the protocol interface.
The UEFI specification does not know of such a function.
It is not possible to implement InstallProtocolInterface with the
current design.
With the patch the protocol interface itself is stored in the list
of installed protocols of an efi_object instead of an open function.
