Fix a leak where a scratch buffer was not freed when reading from the

Browse Source 
/dev/?random devices.  This appears to have been missed when the code
was brought across from the i386.  (This should fix the "world build
hangs with everything waiting on 'temp' problem.)

Also add some iovec fixup code in the error path which seems to have
been similarly fixed.

There are a number of other differences between the i386 and alpha
version which have not been examined.  This code should still be
considered suspect.
