ide-tape: fix proc warning

ide_tape_chrdev_get() was missing an ide_device_get() refcount increment
which lead to the following warning:

Instead of trivially fixing it by adding the missing call,
ide_tape_chrdev_get() and ide_tape_get() were merged into one function
since both were almost identical. The only difference was that
ide_tape_chrdev_get() was accessing the ide-tape reference through the
idetape_devs[] array of minors instead of through the gendisk.

Accomodate that by adding two additional parameters to ide_tape_get() to
annotate the call site and invoke the proper behavior.

As a result, remove ide_tape_chrdev_get().
