  scst: Avoid that smatch complains about dead code
  
  The panic() function that implements BUG() has been declared with attribute
  noreturn in some RHEL 5 kernel headers and also in the RHEL 6 kernel headers.
  Smatch warns about dead code if any code follows a function that has been
  declared with attribute noreturn. Hence add a few preprocessor statements to
  suppress the smatch warning when building against an upstream kernel or when
  building against RHEL 6 or later.
