Xiaohui Zhang 0eeec1a8b0 nfc: nfcmrvl: Fix memory leak in nfcmrvl_play_deferred 
[ Upstream commit 8a4d480702b71184fabcf379b80bf7539716752e ]

Similar to the handling of play_deferred in commit 19cfe912c3
("Bluetooth: btusb: Fix memory leak in play_deferred"), we thought
a patch might be needed here as well.

Currently usb_submit_urb is called directly to submit deferred tx
urbs after unanchor them.

So the usb_giveback_urb_bh would failed to unref it in usb_unanchor_urb
and cause memory leak.

Put those urbs in tx_anchor to avoid the leak, and also fix the error
handling.

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.
