NFC: st21nfca: fix double free
[ Upstream commit 99a8efbb6e30b72ac98cecf81103f847abffb1e5 ]
The variable nfcid_skb is not changed in the callee nfc_hci_get_param()
if error occurs. Consequently, the freed variable nfcid_skb will be
freed again, resulting in a double free bug. Set nfcid_skb to NULL after
releasing it to fix the bug.
