6b020ed078 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.
