Subject: [PATCH] vmm: Fix KvmInterruptManager when base is different from 0

When the base InterruptIndex is different from 0, the loop allocating
GSI and HashMap entries won't work as expected. The for loop needs to
start from base, but the limit must be base+count so that we allocate
a number of "count" entries.
