[PATCH] Fix compliation with systemtap 1.3

[Matthias Bolte <matthias.bolte@xxxxxxxxxxxxxx>]

Version 1.3 uses this macro

  #define STAP_CAST(t) (size_t)t

that breaks if t is a function. For that to work it should probably
look like this

  #define STAP_CAST(t) ((size_t)(t))

In systemtap 1.4 this was completely rewritten.

Anyway, before commit df0b57a95a767c t was always a variable, but now
also a function is used here, namely virNetSASLSessionGetIdentity.

Use an intermediate variable to avoid this problem.
