[ofa-general] [PATCH] mlx4: Add missing FW status return code.

[Jack Morgenstein]

mlx4: Add missing FW status return code.

Added ICM_ERROR status code.
In mapping to errno's, -ENFILE seems closest.

This is in preparation for providing more detailed log info using
mlx4_err() in low-level driver when a non-zero status is returned.
