Most error branches following the call to npe_request contain a call to
npe_request. This patch add a call to npe_release to error branches
following the call to npe_request that do not have it.

This issue was found with Hector.

 If I am right in thinking that these call to npe_release are missing, another
 solution would be to jump to err since the rest of the code does it.
