Rename kzalloc-simple to zalloc-simple since now the rule is not
specific to kzalloc function only, but also to many other zero memory
allocating functions specified in the rule.

There are many instances where memory is allocated using regular
allocator functions immediately followed by setting the allocated
memory to 0 value using memset.

We already have zero memory allocator functions to set the memory to
0 value instead of manually setting it using memset.

Therefore, use zero memory allocating functions instead of regular
memory allocators followed by memset 0 to remove redundant memset and
make the code more cleaner and also reduce the code size.

E.g., --no_show_diff is now --no-show-diff

This semantic patch replaces a pair of calls to kmalloc and memset
by a single call to kzalloc.

It only looks for simple cases to avoid false positives.
