Various callers (all the typec_altmode_ops) take the port-lock just for the tcpm_queue_vdm() call. Add a new tcpm_queue_vdm_unlocked() helper which takes the lock, so that its callers don't have to do this themselves. This is a preparation patch for fixing an AB BA lock inversion between the tcpm code and some altmode drivers.

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.
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.
