src: Use initial_lapicid() instead of open coding it

Since initial_lapicid() returns an unsigned int, change the type of the
local variables the return value gets assigned to to unsigned int as
well if applicable. Also change the printk format strings for printing
the variable's contents to %u where it was %d before.
