[PATCH 3/5] efi_loader: disconnect all controllers when uninstalling a protocol

[Ilias Apalodimas]

When we are trying to uninstall a protocol interface from a controller
handle we are trying to disconnect drivers related to that protocol.
However, when we call efi_disconnect_all_drivers() we pass the protocol
GUID.  If 2 different drivers are using the same protocol interface and
one of them can't be stopped (e.g by returning EFI_DEVICE_ERROR) we
should stop uninstalling it.

Instead of explicitly passing the protocol GUID, pass NULL as an argument.
That will force efi_get_drivers() to return all drivers consuming the
interface regardless of the protocol GUID.
While at it call efi_disconnect_all_drivers() with a handle instead of
the efiobj
