Subject: [PATCH AUTOSEL 5.11 14/61] net: intel: iavf: fix error return code of iavf_init_get_resources()

From: Jia-Ju Bai <baijiaju1990@...il.com>

[ Upstream commit 6650d31f21b8a0043613ae0a4a2e42e49dc20b2d ]

When iavf_process_config() fails, no error return code of
iavf_init_get_resources() is assigned.
To fix this bug, err is assigned with the return value of
iavf_process_config(), and then err is checked.
