nfc: nci: Fix kcov check in nci_rx_work()
mainline inclusion from mainline-v6.9-rc1 commit 19e35f24750ddf860c51e51c68cf07ea181b4881 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9QG8F CVE: CVE-2024-35915 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=19e35f24750ddf860c51e51c68cf07ea181b4881 -------------------------------- Commit 7e8cdc97 ("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 commit d24b03535e5e ("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.
