audit: fix type of sessionid in audit_set_loginuid()
audit: fix type of sessionid in audit_set_loginuid()

sfr pointed out that with CONFIG_UIDGID_STRICT_TYPE_CHECKS set the audit
tree would not build.  This is because the oldsessionid in
audit_set_loginuid() was accidentally being declared as a kuid_t.  This
patch fixes that declaration mistake.

Example of problem:
kernel/auditsc.c: In function 'audit_set_loginuid':
kernel/auditsc.c:2003:15: error: incompatible types when assigning to
type 'kuid_t' from type 'int'
  oldsessionid = audit_get_sessionid(current);
