qlogicpti: Remove slash in QlogicPTI irq name

qlogicpti driver registers its irq with a name containing slash.
This results in 

[   71.049735] WARNING: at fs/proc/generic.c:316 __xlate_proc_name+0xa8/0xb8()
[   71.132815] name 'Qlogic/PTI'

because proc_mkdir with the name of the irq fails. Fix it by just 
removing the slash from irq name. Discovered and tested on real hardware 
(Sun Ultra 1).
