NFC: st21nfca: fix st21nfca_get_iso14443_3_uid data copy
st21nfca_get_iso14443_3_uid() does not correctly copy the uid from
uid_skb->data to its gate parameter. "gate = uid_skb->data;" only
puts a pointer to uid_skb->data to the local variable gate.
This means that in st21nfca_hci_target_from_gate() the content
of "u8 uid[NFC_NFCID1_MAXSIZE]" local variable is never initialized
before being used in memcpy(target->nfcid1, uid, len).
Fix this by replacing the local variable assignment with a memcpy.
This was found by compiling Linux with
"gcc -Wunused-but-set-parameter".
