Yes we can... remove all those pnd->pdc->transceive() from nfc.c.

Browse source 
Within the ongoing effort to improve the NFC devices abstraction, and now that
pn53x_transceive() does not fail when it reads a response that has no
status-code, do not call directly pnd->pdc->transceive() from nfc.c.  In a
mid-term future this will be changed again, and calling pn53x_transceive() from
nfc.c will be forbiden, in favor of colling some pnd->transceive() function,
but that's another part of the story.

Of course, it changes the API one more and it's not going to be the last time
in this branch.
