CRED: Fix kernel panic upon security_file_alloc() failure.
commit 78d2978874e4e10e97dfd4fd79db45bdc0748550 upstream.
In get_empty_filp() since 2.6.29, file_free(f) is called with f->f_cred == NULL
when security_file_alloc() returned an error. As a result, kernel will panic()
due to put_cred(NULL) call within RCU callback.
Fix this bug by assigning f->f_cred before calling security_file_alloc().
