block,ide: simplify bdops->set_capacity() to ->unlock_native_capacity()
bdops->set_capacity() is unnecessarily generic. All that's required
is a simple one way notification to lower level driver telling it to
try to unlock native capacity. There's no reason to pass in target
capacity or return the new capacity. The former is always the
inherent native capacity and the latter can be handled via the usual
device resize / revalidation path. In fact, the current API is always
used that way.
Replace ->set_capacity() with ->unlock_native_capacity() which take
only @disk and doesn't return anything. IDE which is the only current
user of the API is converted accordingly.
