net: qed: invoke err notify on critical areas 

In a number of critical places not only debug trace should be printed,
but the appropriate hw error condition should be raised and error
handling/recovery should start.

Introduce our new qed_hw_err_notify invocation in these places to
record and indicate critical error conditions in hardware.
