nfc: pn533: prevent potential memory corruption
[ Upstream commit ca4d4c34ae9aa5c3c0da76662c5e549d2fc0cc86 ]
If the "type_a->nfcid_len" is too large then it would lead to memory
corruption in pn533_target_found_type_a() when we do:
memcpy(nfc_tgt->nfcid1, tgt_type_a->nfcid_data, nfc_tgt->nfcid1_len);
Fixes: c3b1e1e8a76f ("NFC: Export NFCID1 from pn533")
