mailbox: mailbox-test: Fix debugfs_create_dir error checking

The debugfs_create_dir() function returns ERR_PTR() on error, not NULL.
The current null-check fails to catch errors.

Use IS_ERR() to correctly check for errors.

Fixes: 8ea4484d0c2b ("mailbox: Add generic mechanism for testing Mailbox Controllers")
