x86/apic: Switch wait_for_init_deassert() to a bool flag

Browse Source 
Now that there is only a single wait_for_init_deassert()
function, just convert the member of struct apic to a bool to
determine whether we need to wait for init_deassert to become
non-zero.

There are no more callers of default_wait_for_init_deassert(),
so fold it into the caller.
