[PATCH v5 03/18] timer: Move store of next event into __next_timer_interrupt()

[Anna-Maria Behnsen <anna-maria@linutronix.de>]

Both call sides of __next_timer_interrupt() store return value directly in
base->next_expiry. Move the store into __next_timer_interrupt() and to make
purpose more clear, rename function to next_expiry_recalc().

No functional change.
