libblkid: reduce probing area for crazy CDROMs

Linux kernel reports devices greater than area readable by read(2).
The readable area is usually 2-3 CD blocks smaller (CD block is
2048-bytes) than size returned by BLKGETSIZE. This patch checks for
this issues to avoid I/O errors in probing functions.
