Johannes Berg 1928ecab62 mac80211: fix and simplify mesh locking 
The locking in mesh_{mpath,mpp}_table_grow not only
has an rcu_read_unlock() missing, it's also racy
(though really only technically since it's invoked
from a single function only) since it obtains the
new size of the table without any locking, so two
invocations of the function could attempt the same
resize.

Additionally, it uses synchronize_rcu() which is
rather expensive and can be avoided trivially here.

Modify the functions to only use the table lock
and use call_rcu() instead of synchronize_rcu().
