Michael Thalmeier 571dcbeb8e net: nfc: nci: Fix parameter validation for packet data

Since commit 9c328f5474 ("net: nfc: nci: Add parameter validation for
packet data") communication with nci nfc chips is not working any more.

The mentioned commit tries to fix access of uninitialized data, but
failed to understand that in some cases the data packet is of variable
length and can therefore not be compared to the maximum packet length
given by the sizeof(struct).
