Subject: [PATCH] kernel/irq/proc.c: set MAX_NAMELEN 11 instead of 10 which
 express the maximize size of "%d" or "%u".

Theoretically, the maximize size of "%d" or "%u" is 11 (10 + '\0'), so
need set MAX_NAMELEN 11 instead of 10.

In real world, it may not cause issue, but still recommend to fix this
'theoretical' bug (especially original definition already considered
about 'theoretical' using).
