net/ice/base: propagate errors from functions

There could be an error returned from ice_fill_adv_dummy_packet()
so we need to propagate that to the caller. Additionally, the
call to ice_flow_xtract_pkt_flags() could also return an error so
we need to propagate it as well.

Also add in the correct offsets for GENEVE and VXLAN_GPE to the
dummy packets.

net/ice/base: fix mask for checking protocol header

Before this patch, the logic of protocol header checking only support
non-tunneled packet. This patch remove the inner protocol in L3/L4 RSS
seg hdr mask and change the protocol header validation to reflect this.
So, for ice_add_rss_cfg(), the last parameter addl_hdrs could specify
the protocol header for tunnel.

ethdev: do nothing if all-multicast mode is applied again

Since driver callbacks return status code now, there is no necessity
to enable or disable all-multicast mode once again if it is already
successfully enabled or disabled.

Configuration restore at startup tries to ensure that configured
all-multicast mode is applied and start will return error if it fails.

Also it avoids theoretical cases when already configured all-multicast
mode is applied once again and fails. In this cases it is unclear
which value should be reported on get (configured or opposite).
