reflog expire: refactor & use "tip_commit" only for UE_NORMAL

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 into a one-line ternary instead.
