error-inject: use IS_ERR() check for debugfs_create_file()

Browse Source 
debugfs_create_file() returns an error pointer on failure, never NULL, so
the !file check in ei_debugfs_init() never triggers and the
debugfs_remove() cleanup cannot run.

Use IS_ERR() and propagate the actual error via PTR_ERR().
