nfc: nci: Fix kcov check in nci_rx_work()
Commit7e8cdc9714
("nfc: Add KCOV annotations") added kcov_remote_start_common()/kcov_remote_stop() pair into nci_rx_work(), with an assumption that kcov_remote_stop() is called upon continue of the for loop. But commitd24b03535e
("nfc: nci: Fix uninit-value in nci_dev_up and nci_ntf_packet") forgot to call kcov_remote_stop() before break of the for loop. Reported-by: syzbot <syzbot+0438378d6f157baae1a2@syzkaller.appspotmail.com> Closes: https://syzkaller.appspot.com/bug?extid=0438378d6f157baae1a2 Fixes:d24b03535e
