USB: devio: Properly do access_ok() checks ...
access_ok() checks must be done on every part of the userspace structure
that is accessed. If access_ok() on one part of the struct succeeded, it
does not imply it will succeed on other parts of the struct. (Does
depend on the architecture implementation of access_ok()).
This changes the __get_user() users to first check access_ok() on the
data structure.
