rtnl: zero request message headers

For route netlink request messages having a header struct, uc_nl_request()
invokes nlmsg_reserve() to reserve room for the struct data but the
nlmsg_reserve() function only zeroes additional alignment bytes, not the
actual reserved buffer space.

Extend the existing logic to explicitly zero out the reserved header space
in order to avoid sending uninitialized struct member values to the kernel.
