timers: Simplify calc_index()

The level granularity round up of calc_index() does:

(x + (1 << n)) >> n

which is obviously equivalent to

(x >> n) + 1

but compilers can't figure that out despite the fact that the input range
is known to not cause an overflow. It's neither intuitive to read.

Just write out the obvious.

timers: Initialize base::next_expiry_recalc in timers_prepare_cpu()

When base::next_expiry_recalc is not initialized to false during cpu
bringup in HOTPLUG_CPU and is accidently true and no timer is queued in the
meantime, the loop through the wheel to find __next_timer_interrupt() might
be done for nothing.

Therefore initialize base::next_expiry_recalc to false in
timers_prepare_cpu().

Merge tag 'timers-urgent-2022-04-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull timer fixes from Thomas Gleixner:
"A small set of fixes for the timers core:

- Fix the warning condition in __run_timers() which does not take
into account that a CPU base (especially the deferrable base) never
has a timer armed on it and therefore the next_expiry value can
become stale.

- Replace a WARN_ON() in the NOHZ code with a WARN_ON_ONCE() to
prevent endless spam in dmesg.

- Remove the double star from a comment which is not meant to be in
kernel-doc format"

timers: Fix warning condition in __run_timers()

When the timer base is empty, base::next_expiry is set to base::clk +
NEXT_TIMER_MAX_DELTA and base::next_expiry_recalc is false. When no timer
is queued until jiffies reaches base::next_expiry value, the warning for
not finding any expired timer and base::next_expiry_recalc is false in
__run_timers() triggers.

To prevent triggering the warning in this valid scenario
base::timers_pending needs to be added to the warning condition.
