[PATCH] Locking tweaks for rl(4) and re(4)

[John Baldwin]

Patch fixes the drivers to use MPSAFE callouts using callout_init_mtx() and 
removes rl_unit from the softc by fixing re(4) printfs.  It also fixes some 
minor locking nits in re(4) and fixes ifmedia locking on both drivers.  
Please test.  Thanks!
