Improve error message when device is in use.

[alimhassam]

Exclusively lock the device even on Edison (when customCS is set),
and propagate the error message when lock couldn't be aquired.

Got tired of messing my loop get when querying the pump while the loop was also accessing the radio, this allows the second command to fail with the correct error message without corrupting the first call.

Applied, thanks.
