RDMA/nes: Correct CDR loop filter setting for port 1

Browse Source 
In commit 1b949324 ("RDMA/nes: Fix SFP+ PHY initialization") there is
a mistake in the clean up code that removed port 1 CDR loop filter
settings for 10G cards other than CX4.  Put the correct setting back
for appropriate PHY types.
