ASoC: SOF: Rename snd_sof_get_status() and add kernel log level parameter 

The snd_sof_get_status() is not the best name for a function which in fact
is tasked to print out DSP oops and stack. Rename it to
sof_print_oops_and_stack().

At the same time add a new parameter to specify the desired kernel log
level to be used for the prints.

When updating the users of the function, pass KERN_ERR for now to make sure
that there is no functional change happens.
