sdp: Remove Linux build files.

They aren't useful here, and Linux seems to have largely abandoned SDP
anyway.

-config INFINIBAND_SDP

-	---help---
-	  Support for Sockets Direct Protocol (SDP).  This provides
-          sockets semantics over InfiniBand via address family
-          AF_INET_SDP (address family 27).  You can also LD_PRELOAD the
-          libsdp library from <http://openib.org> to have standard
-          sockets applications use SDP.

-config INFINIBAND_SDP_DEBUG
-	bool "Sockets Direct Protocol debugging"
-	depends on INFINIBAND_SDP
-	---help---
-	  This option causes debugging code to be compiled into the
-	  SDP driver.  The output can be turned on via the debug_level
-	  module parameter  (which can also be set through sysfs after the
-	  driver is loaded).

-config INFINIBAND_SDP_DEBUG_DATA
-        bool "Sockets Direct Protocol data path debugging"
-        depends on INFINIBAND_SDP_DEBUG
-        ---help---
-          This option compiles debugging code into the data path
-          of the SDP driver.  The output can be turned on via the
-          data_debug_level module parameter; however, even with output
-          turned off, this debugging code will have some performance
-          impact.
