Fix error handling of v4l2_ctrl creation by inspecting the ctrl.error flag
instead of testing for each returned value correctness.
As reported by Dan Carpenter returning PTR_ERR() on the v4l2_ctrl_new_std()
return value is also wrong, as that function return NULL on error.
While at there re-order the cleanup path to respect the operation inverse
order.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
