Removed compiler warning for converting bool 'false' to pointer 'void *'

-In the function sensor_get_sensor() in src/libsensord/client.cpp boolean 'false' was being converted to void *
This was showing as a warning at compile time. For returning failed cases, NULL should be returned.
The call to sensor_info_to_sensor in this function also returns NULL when failed.
-Tested the code after change. Seems to be working fine.
