x86/irq: Add and use NR_EXTERNAL_VECTORS and NR_SYSTEM_VECTORS
Add defines for the number of external vectors and number of system vectors instead of requiring the use of (FIRST_SYSTEM_VECTOR - FIRST_EXTERNAL_VECTOR) and (NR_VECTORS - FIRST_SYSTEM_VECTOR) respectively. Clean up the usage sites. Signed-off-by: H.
