Add judgment on SR_MBF and FSR_RXCOUNT. In PIO mode, if don't use CONT to keep cs selected in one transfer, the transfer will go wrong. FCIE will be set after one frame transfer finish. If use CONT, the frame refer to the whole data in one transfer. If don't use CONT, the frame refer to one byte of whole data. This will cause the transfer ending early. This patch add a register reading in isr function, it might lead to a slight decrease in the max transmission speed in PIO mode.

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.
