Subject: igb: check memory allocation failure
From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
[ Upstream commit 18eb86362a52f0af933cc0fd5e37027317eb2d1c ]
Check memory allocation failures and return -ENOMEM in such cases, as
already done for other memory allocations in this function.
This avoids NULL pointers dereference.
