netxen: fix context deletion sequence
o Use D3 reset context deletion for NX2031, it cleans up
more resources in the firmware.
o Release rx buffers after hardware context has been reset.
o Delete tx context after rx context, some firmware control
commands are sent on tx context, so it should be the last
to go.
