hfsplus: fix possible deadlock when handling corrupted extents

A corrupted extent for the extent file itself may try to get an impossible
extent, causing a deadlock if I see it correctly.

Check the inode number after the first_blocks checks and fail if it's the
extent file, as according to the spec the extent file should have no
extent for itself.
