log: Re-order to fix return type deduction
log: Re-order to fix return type deduction

The entry(...) function definition needs to come before the log function since
it depends on knowing the return type of the entry it is generating.
Technically this is never an issue because a concrete log(...) call is
never used before entry(...) is defined, but static analyzers are
unhappy about it.
