[PATCH 5.0 045/122] net: hns3: fix compile error

[Greg Kroah-Hartman]

[ Upstream commit 669efc76b317b3aa550ffbf0b79d064cb00a5f96 ]

Currently, the rules for configuring search paths in Kbuild have
changed, this will lead some erros when compiling hns3 with the
following command:

make O=DIR M=drivers/net/ethernet/hisilicon/hns3

drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_cmd.c:11:10:
fatal error: hnae3.h: No such file or directory

This patch fix it by adding $(srctree)/ prefix to the serach paths.
