ext4: remove useless test and assignment in strtohash functions
On transformation of str to hash, computed value is initialised before first byte modulo 4. But it is already initialised before entering loop and after processing last byte modulo 4. So the corresponding test and initialisation could be removed. Signed-off-by: Damien Guibouret <damien.guibouret@partition-saving.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
