This is primarily an API consolidation and should make things more readable
it replaces var * HZ / 1000 by msecs_to_jiffies(var) which also handles
corner cases correctly.
There is a change of behavior as e.g. for HZ 100, t * HZ / 1000 will
return 0 for t < 10 but msecs_to_jiffies will return at least 1 always.

timeout was being passed as int but assigned from u32/u16 values and used
as unsigned type. This is really only for better readability.

After review of the use locations of mesh_plink_timer_set() and declarations
in sta_info.h this should not be breaking any integer promotions.

Both applied, thanks.
