static keys: Inline the static_key_enabled() function
In the jump label enabled case, calling static_key_enabled()
results in a function call. The function returns the results of
a compare, so it really doesn't need the overhead of a full
function call. Let's make it 'static inline' for both the jump
label enabled and disabled cases.
