Documentation: update /proc/stat "intr" count summary

reviewerPATCH 4/4 Documentation: update /proc/stat "intr" count summary
From: Jan Moskyto Matejka <[email protected]>
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.
This behaviour was added to /proc/stat in commita2eddfa95919a730e0e5ed17e9c303fe5ba249cd.
