[PATCH] adfs: Fix incorrect unsigned return type in adfs_f_getnext()

[Haotian Zhang <vulab@iscas.ac.cn>]

adfs_f_getnext() stores the return value of __adfs_dir_get() into an
unsigned int. Since __adfs_dir_get() may return negative error codes
such as -ENOENT, these values are converted into large positive numbers.

Change the return variable to type int to correctly preserve and return
negative error codes.
