Fedor Pchelkin 7543818e97 wifi: rtw89: usb: fix leak in rtw89_usb_write_port()
When there is an attempt to write data and RTW89_FLAG_UNPLUGGED is set,
this means device is disconnected and no urb is submitted.  Return
appropriate error code to the caller to properly free the allocated
resources.

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 reStructuredText markup notation.

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.
