Fix incorrect error message in xlogreader.c

Browse Source 
When neither BKPIMAGE_HAS_HOLE nor BKPIMAGE_COMPRESSED is set,
DecodeXLogRecord() checks that bimg_len needs to be equal to BLCKSZ.
However, the associated error message reported the data length
associated to a block (DecodedBkpBlock.data_len), and not the length of
the block (DecodedBkpBlock.bimg_len).

Oversight in 57aa5b2bb1, probably due to some copy-paste from the
surroundings.
