[netdrvr] irq handler minor cleanups in several drivers
* use irq_handler_t where appropriate
* no need to use 'irq' function arg, its already stored in a data struct
* rename irq handler 'irq' argument to 'dummy', where the function
has been analyzed and proven not to use its first argument.
* remove always-false "dev_id == NULL" test from irq handlers
* remove pointless casts from void*
* declance: irq argument is not const
* add KERN_xxx printk prefix
* fix minor whitespace weirdness
