3ef5eb424e IDE: Remove unused code
Remove some code which has been made obsolete and hasn't worked properly
before anyway.  Part of the infrastructure may be reintroduced in a
follow up patch to implement a working command aborting facility.

79e36a9f54 IDE: Fix HDIO_DRIVE_RESET handling
Currently, the code path executing an HDIO_DRIVE_RESET ioctl is broken
in various ways.  Most importantly, it is treated as an out of band
request in an illegal way which may very likely lead to system lock ups.
Use the drive's request queue to avoid this problem (and fix a locking
issue for free along the way).

This saves us the overhead of a function call and the function is small enough
