The nci_ctrl_hdr.plen field us u8, so checkign if it is bigger than
NCI_MAX_PAYLOAD_SIZE does not make any sense. Fix warning reported by
Smatch:
drivers/nfc/nfcmrvl/i2c.c:52 nfcmrvl_i2c_read() warn:
impossible condition '(nci_hdr.plen > 255) => (0-255 > 255)'

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.
