bonding: quit messing with IOCTL

Browse Source 
The only remaining users are issuing SIOCGMIIPHY and SIOCGMIIREG,
neither of which deals with userland pointers.  Simply calling
->ndo_do_ioctl() is fine; no messing with set_fs() is needed.
It used to mess with SIOCETHTOOL, which would've needed set_fs(),
but that has been killed in "[NET] ethtool ops are the only way"
