  Prevent data corruption in dvbchannel.cpp causing hang

m_is_open was being corrupted by multiple simultaneous modifications,
leading to it managing to create infinite loops within its underlying
data structure. This patch extends the locking of m_hw_lock to cover
all uses of m_is_open, preventing issues.
