xfs: xfs_rtbuf_get should check the bmapi_read results
The xfs_rtbuf_get function should check the block mapping it gets back
from bmapi_read. If there are no mappings or the mapping isn't a real
extent, we should return -EFSCORRUPTED rather than trying to read a
garbage value. We also require realtime bitmap blocks to be real,
written allocations.
