Fix hfsplus oops on image without extents
Fix an oops with a corrupted hfs+ image.
See http://bugzilla.kernel.org/show_bug.cgi?id=10548 for details.
Problem is that we call hfs_btree_open() from hfsplus_fill_super() to set
HFSPLUS_SB(sb).[ext_tree|cat_tree] Both trees are still NULL at this moment.
If hfs_btree_open() fails for any reason it calls iput() on the page, which
gets to hfsplus_releasepage() which tries to access HFSPLUS_SB(sb).* which is
still NULL and oopses while dereferencing it.
