[PATCH 2/2] lsm: rename variable to avoid shadowing

[Christian Göttsche]

From: Christian Göttsche <cgzones at googlemail.com>

The function dump_common_audit_data() contains two variables with the
name comm: one declared at the top and one nested one.
Rename the nested variable to improve readability and make future refactorings
of the function less error prone.

Reported by clang:

    security/lsm_audit.c:302:10: error: declaration shadows a local variable [-Werror,-Wshadow]
      302 |                                 char comm[sizeof(tsk->comm)];
          |                                      ^
    security/lsm_audit.c:200:7: note: previous declaration is here
      200 |         char comm[sizeof(current->comm)];
          |              ^
