Kernel has few users of pasid_valid() and all but one checks if the process has PASID allocated. The helper takes ioasid_t as the input. Replace the helper with mm_valid_pasid() that takes mm_struct as the argument. The only call that checks PASID that is not tied to mm_struct is open-codded now. This is preparatory patch. It helps avoid ifdeffery: no need to dereference mm->pasid in generic code to check if the process has PASID. Signed-off-by: Kirill A.

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.
