Remove uses of open-coded value 16 in x86's interrupt management code
to enhance readability.
  
Patch 0 makes a cosmetic rename NR_ISAIRQS -> NR_ISA_IRQS as per
code review [1].

Patch 1 makes use of NR_ISA_IRQS in the code where necessary.
 
Patch 2 adds new symbol APIC_VECTOR_VALID and makes use of it.
 
No functional changes.
