net: Un-hide lockdep_sock_is_held() for !LOCKDEP 



Currently, variables used only within lockdep expressions are flagged
as unused, requiring that these variables' declarations be decorated
with either #ifdef or __maybe_unused.  This results in ugly code.
This commit therefore causes the lockdep_sock_is_held() function to be
visible even when lockdep is not enabled, thus removing the need for
these decorations.  This approach further relies on dead-code elimination
to remove any references to functions or variables that are not available
in non-lockdep kernels.
