[PATCH] makes 'find' work with Amiga RR enhanced ISO CD's

this patch fixes a bug in the isofs, or rather hides a bug in numerous
CDs I own which have been manufactured with the Amiga RockRidge
extensions. Those CD's contain RockRidge PX entries, but the n_links
field for directories is always 2 (even if the directory contains
entries), so 'find' is unable to examine the CD (this 'bug' is
mentioned in inode.c, too). This patch makes the 2 into a 1, so 'find'
is forced to do a real directory scan.
