Jan KaraandGreg Kroah-Hartman a64d8972f0 udf: Fix inode_getblk() return value ...

commit 6afdc60ec3 upstream.

Smatch noticed that inode_getblk() can return 1 on successful mapping of
a block instead of expected 0 after commit b405c1e58b ("udf: refactor
udf_next_aext() to handle error"). This could confuse some of the
callers and lead to strange failures (although the one reported by
Smatch in udf_mkdir() is impossible to trigger in practice). Fix the
return value of inode_getblk().
