             Extend instance locking in HDHomeRun stream handler

 Extend the instance locking already present in HDHRStreamHandler
 functions TunerGet and TunerSet to GetTunerStatus.
 This fixes a segfault in libhdhomerun, reported in ticket #13519,
 that appeared when doing a UK DVB-T/T2 scan with offset frequencies.
 The segfault happened because GetTunerStatus was called from the
 HDHRSignalMonitor in a different thread than the TunerGet/TunerSet
 functions.
 Extend the instance locking also to the HDHRStreamHandler::run function
 where the libhdhomerun functions are called. This should fix the segfault
 in the mythbackend startup as reported in ticket #9027.
