If one or both sensor buffers could not be initialized, either due to missing hardware support or due to some error during probing, the resume handler will encounter undefined behaviour when attempting to lock buffers then protected by an uninitialized or destroyed mutex. Fix this by introducing a "active" flag which is set during probe, and only invalidate buffers which where flaged as "active". Tested on a Dell Inspiron 3505.
