[PATCH 26/62] ixgbe: Use static const

[Joe Perches]

Using static const generally increases object text and decreases data size.
It also generally decreases overall object size.

   text	   data	    bss	    dec	    hex	filename
  31444	     56	   6552	  38052	   94a4	drivers/net/ixgbe/ixgbe_ethtool.o.new
  30905	    560	   6552	  38017	   9481	drivers/net/ixgbe/ixgbe_ethtool.o.old

Make single file scope definition for register_test_patterns.
Rename _test to register_test_patterns.
