[PATCH] hw/vfio/common: Fix a small boundary issue of a trace

[chenxiang via]

From: Xiang Chen <chenxian...@hisilicon.com>

Right now the trace of vfio_region_sparse_mmap_entry is as follows:
vfio_region_sparse_mmap_entry sparse entry 0 [0x1000 - 0x9000]
Actually the range it wants to show is [0x1000 - 0x8fff]???so fix it.
