[PATCH net-next 7/7] net: hns3: remove unnecessary check in hns3_dbg_read()

[Huazhong Tan]

Clang warns:

drivers/net/ethernet/hisilicon/hns3/hns3_debugfs.c:499:28: warning:
address of array 'filp->f_path.dentry->d_iname' will always evaluate
to 'true' [-Wpointer-bool-conversion]
        if (!filp->f_path.dentry->d_iname)

This check is unnecessary, so remove it.
