Subject: [PATCH 4.14 174/218] net/mlx4_en: Fix wrong return value on ioctl EEPROM query failure

From: Gal Pressman <gal@...dia.com>

[ Upstream commit f5826c8c9d57210a17031af5527056eefdc2b7eb ]

The ioctl EEPROM query wrongly returns success on read failures, fix
that by returning the appropriate error code.
