media: cec: core: avoid recursive cec_claim_log_addrs
[ Upstream commit 47c82aac10a6954d68f29f10d9758d016e8e5af1 ]
Keep track if cec_claim_log_addrs() is running, and return -EBUSY
if it is when calling CEC_ADAP_S_LOG_ADDRS.
This prevents a case where cec_claim_log_addrs() could be called
while it was still in progress.
