Initialize m_sampleRate to zero so LocalInput starts with a defined sample rate before one is configured. The member was previously left uninitialized, allowing sample rate access to use an indeterminate value. This resolves the uninitialized member finding reported by Coverity (UNINIT_CTOR).

Local input plugin
Introduction
This input sample source plugin gets its samples from a Local Sink channel in another device set.
Interface
The top and bottom bars of the device window are described here
1: Start/Stop
Device start / stop button.
- Blue triangle icon: device is ready and can be started
- Green square icon: device is running and can be stopped
3: Frequency
This is the center frequency in Hz sent from the Local Sink channel instance and corresponds to the center frequency of reception.
4: Stream sample rate
Stream I/Q sample rate in kS/s
5: Auto remove DC component
Filters out the possible DC component. You use this if you notice a spike in the center of the pass band.
6: Auto make I/Q balance
Re-balances the I and Q channels. You use this if you notice ghost artifacts symmetric around the center frequency.
