ecryptfs: Fix improper mknod pairing of start_creating()/end_removing()

ecryptfs: Fix improper mknod pairing of start_creating()/end_removing()

The ecryptfs_start_creating_dentry() function must be paired with the
end_creating() function. Fix ecryptfs_mknod() so that end_creating() is
properly called in the return path, instead of end_removing().
