bonding: fix error unwind in bonding_store_bonds
Fixed an error unwind in bonding_store_bonds that didn't release the locks it held, and consolidated unwinds into a common block at the end of the function. Bug reported by Pavel Emelyanov <xemul@openvz.org>, who provided a different fix. Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
