Subject: [PATCH] bonding/alb: return -ENOMEM when kmalloc failed

The driver is using -1 instead of the -ENOMEM defined macro to
specify that a buffer allocation failed. Using the correct error
code is more intuitive.

Smatch tool warning:
drivers/net/bonding/bond_alb.c:850 rlb_initialize() warn: returning -1
instead of -ENOMEM is sloppy

No functional change, just more standardized.
