Subject: [PATCH] ionic: Remove unnecessary ternary operator in ionic_debugfs_add_ident

clang warns:

../drivers/net/ethernet/pensando/ionic/ionic_debugfs.c:60:37: warning:
expression result unused [-Wunused-value]
                            ionic, &identity_fops) ? 0 : -EOPNOTSUPP;
                                                         ^~~~~~~~~~~
1 warning generated.

The return value of debugfs_create_file does not need to be checked [1]
and the function returns void so get rid of the ternary operator, it is
unnecessary.
