x86/apic: Simplify X2APIC ID validation
Currently, x2apic_max_apicid==0 means that there is no max APIC id limit.
But, this means that 0 needs to be special-cased.
Designate UINT_MAX to mean unlimited so that a plain old less than or equal
compare works and there is no special-casing. Replace the 0 initialization
with UINT_MAX.
