rcu: Force boolean subscript for expedited stall warnings
commit ec3833ed02ae6ef2a933ece9de7cbab0c64c699e upstream.
The cpu_online() function can return values other than 0 and 1, which
can result in subscript overflow when applied to a two-element array.
This commit allows for this behavior by using "!!" on the return value
from cpu_online() when used as a subscript.
