USB: serial: ark3116: fix register-accessor error handling
commit 9fef37d7cf170522fb354d6d0ea6de09b9b16678 upstream.
The current implementation failed to detect short transfers, something
which could lead to bits of the uninitialised heap transfer buffer
leaking to user space.
Fixes: 149fc791a452 ("USB: ark3116: Setup some basic infrastructure for new ark3116 driver.")
Fixes: f4c1e8d597d1 ("USB: ark3116: Make existing functions 16450-aware and add close and release functions.")
