timers: Move store of next event into __next_timer_interrupt()
Both call sites of __next_timer_interrupt() store the return value directly
in base->next_expiry. Move the store into __next_timer_interrupt() and to
make its purpose more clear, rename the function to next_expiry_recalc().
No functional change.
