Avoid redundant code in PN53x usb and uart drivers.  Since it makes sense to
report errors at the nfc_device_t level, pass it directly to
pn53x_transceive().

Programs using the libnfc MAY use pn53x_transceive() to communicate with a NFC
device, and SHALL not use anymore pnd->pdc->transceive().  Code in the library
itself SHOULD avoid calling pnd->pdc->transceive(), so such construct have been
updated accordingly.
