char: misc: Fix improper and inaccurate error code returned by misc_init()
misc_init() returns -EIO for __register_chrdev() invocation failure, but:
- -EIO is for I/O error normally, but __register_chrdev() does not do I/O.
- -EIO can not cover various error codes returned by __register_chrdev().
Fix by returning error code of __register_chrdev().
