switch kernel_sendmsg() and kernel_recvmsg() to iov_iter_kvec()
For kernel_sendmsg() that eliminates the need to play with setfs(); for kernel_recvmsg() it does *not* - a couple of callers are using it with non-NULL ->msg_control, which would be treated as userland address on recvmsg side of things. In all cases we are really setting a kvec-backed iov_iter, though. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
