[PATCH][next] nfc: pn533: Avoid -Wflex-array-member-not-at-end warnings

[Gustavo A. R. Silva]

-Wflex-array-member-not-at-end was introduced in GCC-14, and we are
getting ready to enable it, globally.

Remove unnecessary flex-array member `data[]`, and with this fix
the following warnings:

drivers/nfc/pn533/usb.c:268:38: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
drivers/nfc/pn533/usb.c:275:38: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]
