I actually think that we should try to unite pc/fs error handling as much
as possible as it shouldn't really matter if i.e. READ command came through
fs or pc request - the error handling w.r.t. hardware should be the same
(at the moment it is not always the case - the most blatant example of this
disrepancy is handling of NOT_READY sense key for WRITE commands).

When I was suggesting factoring out error handling I rather meant moving
out _everything_ after OK_STAT() (sorry for the confusion).  On the second
thought we may do it in even simpler way by moving:

...
	/* check for errors */
	stat = ide_read_status(drive);

	if (stat_ret)
		*stat_ret = stat;

	if (OK_STAT(stat, good_stat, BAD_R_STAT))
		return 0;
...

to cdrom_decode_status() users and passing as an argument 'stat' instead
of 'good_stat' and 'stat_ret'.

Therefore I skipped this patch (and also patch #4) for now.
