Add an intermediate variable for "tip_commit" in
reflog_expiry_prepare(), and only add it to the struct if we're
handling the UE_NORMAL case.
The code behaves the same way as before, but this makes the control
flow clearer, and the shorter name allows us to fold a 4-line i/else
int a one-line terany instead.
