I suspect checkpatch would pick up the indentation mess, but
indentation is the least of this patch's problems.
if that alloc_skb fails, going around the loop again is pointless, and
harmful. (we'll oops right below that added bracket).
on failure, this should be returning 0 so that the caller
handles the failure appropriately.
