[PATCH] proc: fix documentation for /proc/stat, line "intr"

[Jan Moskyto Matejka <mq@suse.cz>]

The sum at the beginning of line "intr" includes also unnumbered interrupts.
It implies that the sum at the beginning isn't the sum of the remainder of the
line, not even an estimation.

Fixed the documentation to mention that.
