[PATCH v2] xfs: fix endianness error when checking log block crc on big endian platforms

["Darrick J. Wong" <darrick.wong@xxxxxxxxxx>]

Since the checksum function and the field are both __le32, don't
perform endian conversion when comparing the two.  This fixes mount
failures on ppc64.

v2: fix the other crc comparison
