qcacmn: Add a callback to the FW assert function in Spectral module

As Spectral module is loaded before qca_ol module and the FW assert
function is compiled in qca_ol module, FW assert function will be an
unknown symbol when used inside Spectral module.
To fix this, register a callback to the FW assert function and
use that callback in Spectral module.
