open_drive: Don't call set_drive_state to take a drive down, do it
            ourselves.  This breaks a vicious circle which caused
            vinum to dereference a null vp if device nodes were
            missing.

Reported-by:	Brad Chisholm <sasblc@unx.sas.com>

check_drive: Don't take a drive down if it's only referenced.

read_drive: Remove unused variable.
