[RFC 1/6] genhd: update docs for GENHD_FL_UP

[Luis Chamberlain]

The GENHD_FL_UP is used internally so we can know when we can add and
remove partitions, so just clarify that. Right now it has this 1980's
description comparing it to network drivers "ifconfig up" idea, and
that can easily lead to invalid uses.
