[PATCH net-next] bnx2: remove deadcode in bnx2_init_cpus()

[Maxim Korotkov]

The load_cpu_fw function has no error return code
and always returns zero. Checking the value returned by
this function does not make sense.
As a result, bnx2_init_cpus() will also return only zero
Therefore, it will be safe to change the type of functions
to void and remove checking
