net:nfc:digital: Fix a double free in digital_tg_recv_dep_req
[ Upstream commit 75258586793efc521e5dd52a5bf6c7a4cf7002be ]
In digital_tg_recv_dep_req, it calls nfc_tm_data_received(..,resp).
If nfc_tm_data_received() failed, the callee will free the resp via
kfree_skb() and return error. But in the exit branch, the resp
will be freed again.
My patch sets resp to NULL if nfc_tm_data_received() failed, to
avoid the double free.
Fixes: 1c7a4c24fbfd9 ("NFC Digital: Add target NFC-DEP support")
