xfs: don't update lastino for FSBULKSTAT_SINGLE
The kernel test robot found a regression of xfs/054 in the conversion of
bulkstat to use the new iwalk infrastructure -- if a caller set *lastip
= 128 and invoked FSBULKSTAT_SINGLE, the bstat info would be for inode
128, but *lastip would be increased by the kernel to 129.
FSBULKSTAT_SINGLE never incremented lastip before, so it's incorrect to
make such an update to the internal lastino value now.
