Guenter Roeck 85e1cd6e76 hrtimer: Handle failure of tick_init_highres() gracefully 
Commit 75e3b37d05 ("hrtimer: Drop return code of hrtimer_switch_to_hres()")
drops the return code of hrtimer_switch_to_hres(). While doing so, it also
drops the return statement itself on failure. This may cause a system hang.
Seen when running arm:multi_v7_defconfig in qemu with devicetree file
vexpress-v2p-ca9.

Fixes: 75e3b37d05 ("hrtimer: Drop return code of hrtimer_switch_to_hres()")
