net: qed: correct qed_hw_err_notify() prototype

Change the prototype of qed_hw_err_notify() with the following:
* constify "fmt" argument according to printk() declarations;
* anontate it with __cold attribute to move the function out of
  the line;
* annotate it with __printf() attribute;

This eliminates W=1+ warning:

drivers/net/ethernet/qlogic/qed/qed_hw.c: In function
‘qed_hw_err_notify’:
drivers/net/ethernet/qlogic/qed/qed_hw.c:851:3: warning: function
‘qed_hw_err_notify’ might be a candidate for ‘gnu_printf’ format
attribute [-Wsuggest-attribute=format]
 len = vsnprintf(buf, QED_HW_ERR_MAX_STR_SIZE, fmt, vl);
 ^~~

as well as saves some code size:

__printf() will also be helpful with catching bad format strings
and arguments.
