Alan Mikhak bfac8e9f55 nvme-pci: check for NULL return from pci_alloc_p2pmem()
Modify nvme_alloc_sq_cmds() to call pci_free_p2pmem() to free the memory
it allocated using pci_alloc_p2pmem() in case pci_p2pmem_virt_to_bus()
returns null.

Makes sure not to call pci_free_p2pmem() if pci_alloc_p2pmem() returned
NULL, which can happen if CONFIG_PCI_P2PDMA is not configured.

The current implementation is not expected to leak since
pci_p2pmem_virt_to_bus() is expected to fail only if pci_alloc_p2pmem()
returns null. However, checking the return value of pci_alloc_p2pmem()
is more explicit.

README

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.
