[PATCH] qed: fix kzalloc-simple.cocci warnings

[kbuild test robot]

drivers/net/ethernet/qlogic/qed/qed_dcbx.c:1267:13-20: WARNING: kzalloc should 
be used for dcbx_info, instead of kmalloc/memset


 Use kzalloc rather than kmalloc followed by memset with 0

 This considers some simple cases that are common and easy to validate
 Note in particular that there are no ...s in the rule, so all of the
 matched code has to be contiguous
