Fix typo: iff  ==> if

Signed-off-by: Cai Huoqing <redacted>

This is becoming an FAQ ...  "iff" in mathematical English means "if and
only if"; its usage in these documents is correct.

... and yet it's clearly not understood.  Similarly to the [start..end)
convention (also the [start..end[ convention).  Should we deprecate
use of it in kernel documentation, and if so, what should we replace it
with?
