mac80211: Deinline drv_get/set/reset_tsf() 

With this .config: http://busybox.net/~vda/kernel_config_ALLYES_Os

,
after deinlining these functions have sizes and callsite counts
as follows:

drv_get_tsf: 634 bytes, 6 calls
drv_set_tsf: 626 bytes, 2 calls
drv_reset_tsf: 617 bytes, 2 calls

Total size reduction is about 4.2 kbytes.
