87e216294a udhcpc: don't exit after backgrounding on -n -b 
Currently, running "udhcpc -n -b" causes udhcpc to go to background and
then exit after some time unless a lease is obtained.

It's not very useful to do so
as the calling process doesn't know
if the lease was obtained or not anyway.

The code actually tries to favor "-b" over "-n",
but doesn't clear "-n" flag while clearing "-b" after backgrounding.

So, clear "-n" flag after going into background.
This effectively makes "-b" override "-n" completely
and "-n -b" behave the same as "-b".

This allows to override default "-n" option, passed to udhcpc by ifupdown,
without recompiling busybox.

414be6c111 ip link: Fix vlan proto, closes 8261 and 11638 
The proto has to be passed in network byte-order.
While at it allow for
 ip link add link eth0 name eth0.2.24 type vlan proto 802.1ad id 24
 ip link del link eth0 name eth0.2.24 type vlan proto 802.1ad id 24
The del was lacking a dev_str and thus errored out. Fix by using
name/dev counterpart as fallback.

The proto identifier 802.1Q was not recognized, just it's lowercase
variant, fix that too.
