rcu: Clean up code based on review feedback from Josh Triplett, part 3
Whitespace fixes, updated comments, and trivial code movement.
o Fix whitespace error in RCU_HEAD_INIT()
o Move "So where is rcu_write_lock()" comment so that it does
not come between the rcu_read_unlock() header comment and
the rcu_read_unlock() definition.
o Move the module_param statements for blimit, qhimark, and
qlowmark to immediately follow the corresponding
definitions.
o In __rcu_offline_cpu(), move the assignment to rdp_me
inside the "if" statement, given that rdp_me is not used
outside of that "if" statement.
