ocfs2: fix incorrect CPU endianness conversion causing mount failure
Commit 23aab037106d ("ocfs2: fix UBSAN warning in ocfs2_verify_volume()")
introduced a regression bug. The blksz_bits value is already converted to
CPU endian in the previous code; therefore, the code shouldn't use
le32_to_cpu() anymore.
