[PATCH 06/12] nfc: mrvl: skip impossible NCI_MAX_PAYLOAD_SIZE check

[Krzysztof Kozlowski]

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)'
