qcacmn: Print an error message when Agile spectral frequency is 0

When agile spectral frequency is 0 and user tries to start agile spectral
scan, 'A parameter is not initialized' message is thrown from user space
but that message is not enough to identify that agile spectral frequency
is not initialized. To address this, print an error message from driver
when Agile spectral frequency is 0.
