[PATCH] enic: Use kcalloc instead of kzalloc to allocate array

[Thomas Meyer]

The advantage of kcalloc is, that will prevent integer overflows which could
result from the multiplication of number of elements and size and it is also
a bit nicer to read.

The semantic patch that makes this change is available
in https://lkml.org/lkml/2011/11/25/107
