[PATCH] create /proc/ide/hdX/capacity only once

In ide_register_subdriver() create drive->proc entries only if driver is
not idedefault_driver.

[ There won't be /proc/ide/hdX/capacity for devices attached
  to idedefault_driver now, it reported 0x7fffffff previously. ]

Do not create drive->proc entries in create_proc_ide_drives(), they are
added later in ide_register_subdriver().
