Subject: 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.
