[PATCH] net: hns3: avoid -Wpointer-bool-conversion warning

[PATCH] net: hns3: avoid -Wpointer-bool-conversion warning

[Arnd Bergmann]

From: Arnd Bergmann <arnd@arndb.de>

clang points out a redundant sanity check:

drivers/net/ethernet/hisilicon/hns3/hns3_debugfs.c:497:28: error: address of array 'filp->f_path.dentry->d_iname' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion]

This can never fail, so just remove the check.

Fixes: 04987ca1b9b6 ("net: hns3: add debugfs support for tm nodes, priority and qset info")
