Subject: [PATCH] drm/udl: Return correct error code on kmalloc failure

-ENOMEM is correct error code to return on a memory allocation failure
instead of -1.

Smatch Warning:
drivers/gpu/drm/udl/udl_connector.c:27 udl_get_edid_block() warn:
returning -1 instead of -ENOMEM is sloppy

Fixes: a51143001d9e ("drm/udl: Refactor edid retrieving in UDL driver (v2)")
