====================
bonding: get rid of curr_slave_lock

This is the second patch-set dealing with bond locking and the purpose here
is to convert curr_slave_lock into a spinlock called "mode_lock" which can
be used in the various modes for their specific needs. The first three
patches cleanup the use of curr_slave_lock and prepare it for the
conversion which is done in patch 4 and then the modes that were using
their own locks are converted to use the new "mode_lock" giving us the
opportunity to remove their locks.
This patch-set has been tested in each mode by running enslave/release of
slaves in parallel with traffic transmission and miimon=1 i.e. running
all the time. In fact this lead to the discovery of a subtle bug related to
RCU which will be fixed in -net.
Also did an allmodconfig test just in case :-)

v2: fix bond_3ad_state_machine_handler's use of mode_lock and
    curr_slave_lock
