The value is only ever set once in bond_3ad_initialize and only ever
read otherwise. There seems to be no reason to set the variable via
bond_3ad_initialize when setting the global variable will do. Change
ad_ticks_per_sec to a const to enforce its read-only usage.

Notes:
v4:
* remove passing the value of ad_ticks_per_sec on the stack and
set ad_ticks_per_sec and make as const
