crypto: shash - Fix unaligned calculation with short length

upstream commit: f4f689933c63e0fbfba62f2a80efb2b424b139ae

When the total length is shorter than the calculated number of unaligned bytes, the call to shash->update breaks. For example, calling crc32c on unaligned buffer with length of 1 can result in a system crash.
