This function returns zero or -ENOMEM, but because it's type is u16, the
-ENOMEM gets changed to 65524.  None of the callers care, but lets fix
it anyway as a cleanup.

return an error immediately in such a case instead.

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.

 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
