KVM: SVM: Replace hard-coded value 0x1FF with the corresponding macro

Browse source

The lower 9-bit field in EXITINFO2 represents an index into the AVIC
Physical/Logical APIC ID table for a AVIC_INCOMPLETE_IPI #VMEXIT. Since
the index into the Logical APIC ID table is just 8 bits, this field is
actually bound by the bit-width of the index into the AVIC Physical ID
table which is represented by AVIC_PHYSICAL_MAX_INDEX_MASK. So, use that
macro to mask EXITINFO2.Index instead of hard coding 0x1FF in
avic_incomplete_ipi_interception().
