nfc: nci: Fix kcov check in nci_rx_work()

[ Upstream commit 19e35f24750ddf860c51e51c68cf07ea181b4881 ]

Commit 7e8cdc97148c ("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.
