[PATCH] net: ethernet: fix call_kern.cocci warnings

[Julia Lawall]

From: Fengguang Wu <fengguang.wu at intel.com>

Allocation with GFP_KERNEL in code called from the function
geth_resize_freeq with locks held.

Generated by: scripts/coccinelle/locks/call_kern.cocci

 The proposed change of converting the GFP_KERNEL is not necessarily the
 correct one.  It may be desired to unlock the lock, or to not call the
 function under the lock in the first place.
