[PATCH 1/2] rcu: just rename call_rcu_bh instead of making it a macro

[Steven Rostedt]

Seems that I found a box that has a config that passes call_rcu_bh as a
function pointer (see net/sctp/sm_make_chunk.c), so declaring the
call_rcu_bh has a macro function isn't good enough.

This patch makes it just another name of call_rcu for rcupreempt.
