The check for a null inode is redundant since the function
is a callback for exportfs, which will itself crash if
dentry->d_inode or parent->d_inode is NULL. Removing the
null check makes this consistent with other file systems.
Also remove the redundant null dir check too.

Kudos to Jeff Mahoney for reviewing and explaining the error in
my original patch (most of this explanation went into the above
commit message) and David Sterba for pointing out that the dir
check is also redundant.
