[PATCH] ide-generic: Fix no initalization of idx in some case

[Johann Felix Soden <johfel@gmx.de>]

From: Johann Felix Soden <johfel@users.sourceforge.net>

If the slot is already occupied, there should be written 0xff to idx[i].
In the ongoing code and in this case there are no writings to idx[i], so
garbage stays in idx. The kernel get into a endless loop printing:

: I/O resource 0x0-0x0 not free.
Trying to free nonexistent resource <0000000000000000-0000000000000000>
Trying to free nonexistent resource <0000000000000000-0000000000000000>

This patch solves http://article.gmane.org/gmane.linux.ide/28810 .
