rtnetlink: Mask the rta_type when range checking

[ Upstream commit a5b8db91442fce9c9713fcd656c3698f1adde1d6 ]

Range/validity checks on rta_type in rtnetlink_rcv_msg() do
not account for flags that may be set.  This causes the function
to return -EINVAL when flags are set on the type (for example
NLA_F_NESTED).
