[Intel-wired-lan] [PATCH] igb: Fix a memory leak in igb_probe

[Jia-Ju Bai]

In error handling code of igb_probe, the memory adapter->shadow_vfta 
allocated by kcalloc in igb_sw_init is not freed. So when register_netdev 
or igb_init_i2c is failed, a memory leak will occur.
This patch adds kfree to fix it.
