Only called from one place now, so merge it into xfs_buf_alloc_pages(). Because page array allocation is dependent on bp->b_pages being null, always ensure that when the pages array is freed we always set bp->b_pages to null. Also convert the page array to use kmalloc() rather than kmem_alloc() so we can use the gfp flags we've already calculated for the allocation context instead of hard coding KM_NOFS semantics.

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.
