gfs2: avoid inefficient use of crc32_le_shift()
__get_log_header() was using crc32_le_shift() to update a CRC with four
zero bytes. However, this is about 5x slower than just CRC'ing four
zero bytes in the normal way. Just do that instead.
(We could instead make crc32_le_shift() faster on short lengths. But
all its callers do just fine without it, so I'd like to just remove it.)
