[PATCH] crypto: glue_helper: remove redundant check on nbytes < bsize

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

There is a check to see if nbytes < bsize (and a jump to label 'done' if
it is true) inside the proceeding do-while loop so it is impossible for
the second nbytes < bsize check to be true, hence is it redundant and
can be removed. Remove it.
