genirq: Bump the size of the local variable for sprintf() 

GCC is not happy about a sprintf() call on a buffer that might be too small
for the given formatting string.

kernel/irq/debugfs.c:233:26: warning: 'sprintf' may write a terminating nul past the end of the destination [-Wformat-overflow=]

Fix this by bumping the size of the local variable for sprintf().
