Jan Kara 8b1d55e43c udf: Avoid directory type conversion failure due to ENOMEM ...

commit df97f64dfa upstream.

When converting directory from in-ICB to normal format, the last
iteration through the directory fixing up directory enteries can fail
due to ENOMEM. We do not expect this iteration to fail since the
directory is already verified to be correct and it is difficult to undo
the conversion at this point. So just use GFP_NOFAIL to make sure the
small allocation cannot fail.
