mac80211: deinline rate_control_rate_init, rate_control_rate_update
With this .config: http://busybox.net/~vda/kernel_config, after deinlining these functions have sizes and callsite counts as follows: rate_control_rate_init: 554 bytes, 8 calls rate_control_rate_update: 1596 bytes, 5 calls Total size reduction: about 11 kbytes.
