Fix up a couple of small dma_addr handling issues
- don't double-count dma-map-err stat in ionic_tx_map_skb()
or ionic_xdp_post_frame()
- return 0 on error from both ionic_tx_map_single() and
ionic_tx_map_frag() and check for !dma_addr in ionic_tx_map_skb()
and ionic_xdp_post_frame()
- be sure to unmap buf_info[0] in ionic_tx_map_skb() error path
- don't assign rx buf->dma_addr until error checked in ionic_rx_page_alloc()
- remove unnecessary dma_addr_t casts

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.
