lib/crc32.c: fix unused variables warnings

Variables t4, t5, t6 and t7 are only used when CRC_LE_BITS != 32. Fix the following compilation warnings: lib/crc32.c: In function 'crc32_body': lib/crc32.c:77:55: warning: unused variable 't7' lib/crc32.c:77:41: warning: unused variable 't6' lib/crc32.c:77:27: warning: unused variable 't5' lib/crc32.c:77:13: warning: unused variable 't4' Signed-off-by: Thiago Rafael Becker <[email protected]> Cc: "Darrick J.
