bonding: quit messing with IOCTL
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" 9 years ago... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
